| Issue Key | Component | Description |
|---|---|---|
| VER-88926 | UI - Management Console | When you provisioned a new database on Amazon Web Services, the operation failed. This issue has been resolved. |
| VER-89846 | Data Collector | If a notifier was set for some DC tables and then subsequently dropped, it still remained present in those DC table policies. This could cause a very large number of messages in vertica.log and potential node crashes. The issue was resolved by making "DROP NOTIFIER" support the CASCADE logic. Without CASCADE, drop would fail for the notifiers still used by DC tables. |
| VER-89910 | Security | Previously, when configuring a chain of certificates longer than a root CA certificate and a client certificate for internode TLS, the configuration would successfully be applied, but cause the cluster to shut down. This has been fixed. |
| VER-90039 | Kafka Integration | When a notifier was set for the NotifierErrors or NotifierStats Data collector (DC) tables, notifications sent with a Kafka notifier might cause a loop that produced an infinite stream of notifications. This might result in severely degradated node performance. This issue has been resolved. Now, notifications are disabled for these DC tables, and any existing notifiers have been removed from these tables. |
| VER-90092 | Security | In cases of intermittent network connectivity to an LDAP server, Vertica will now retry bind operations. |

|---|---|---|
| VER-89827 | Recovery | Certain rare sequences of memory allocations crashed Vertica. This occurred when you loaded a table with many fields while a node was down and the MaxTieredPoolScale configuration parameter was set to 22 or lower. This issue has been resolved. |
Updated 09/27/2023
| Issue Key | Component | Description |
|---|---|---|
| VER-89337 | Data Collector | In some environments the io_stats system view was empty. The monitoring functionality has been improved with better detection of I/O devices. |

| VER-88498 | Client Drivers - ODBC |
Previously, the connection property FastCursorClose was set to FastCursorClose is now set to |
| VER-88549 | Optimizer | Queries that contained a WITH query that was referred to more than once and also contained multiple distinct aggregates failed with a system error. This issue has been resolved. |
Updated 08/29/2023
| Issue Key | Component | Description |
|---|---|---|
| VER-87777 | Admin Tools, Data Collector | If you revived a database and the EnableDataCollector parameter was set to 1, you could not start the database after it was revived. This issue was resolved. To start the database, disable the cluster lease check. |
| VER-87878 | Catalog Engine |
Previously, when a cluster lost quorum and switched to read-only mode or stopped, some transaction commits in the queue might get processed. However, due to the loss of quorum, these commits might not have been persisted. These "transient transactions" were reported as successful, but they were lost when the cluster restarted. Now, when Vertica detects a transient transaction, it issues a WARNING so you can diagnose the problem, and it creates an event in ACTIVE_EVENTS that describes what happened. |
| VER-87969 | SDK | Previously, you could not compile Vertica UDx builds with GCC compiler version 13 and higher. This issue has been resolved. |
| VER-87972 | Kafka Integration | In some circumstances, there were long timeouts or the process might hang indefinitely when the KafkaAvroParser accessed the Avro Schema Registry. This issue has been resolved. |
| VER-88007 | Execution Engine | Queries with large tables stopped the database because the indices that Vertica uses to navigate the tables consumed too much RAM. This issue has been resolved, and now the indices use less RAM. |
| VER-88128 | EON | The sync_catalog function failed when MinIO communal storage did not meet read-after-write and list-after-write consistency guarantees. A check was added to bypass this restriction. However, if possible, users should ensure their MinIO storage is configured for read-after-write and list-after-write consistency. |
| VER-88207 | Optimizer | In some query plans with segmentation across multiple nodes, Vertica would get an internal optimizer error when trying to prune out unused data edges from the plan. This issue has been resolved. |
| VER-88228 | EON | In rare circumstances, the automatic sync of catalog files to the communal storage stopped working on some nodes. Users could still manually sync with sync_catalog(). The issue has been resolved. |
| VER-88283 | Performance tests | In some cases, the NVL2 function caused Vertica to crash when it returned an array type. This issue has been resolved. |
Updated 07/12/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑87801 | Optimizer | During the planning stage, updates on tables with thousands of columns using thousands of SET USING clauses took a long time. Planning performance for these updates was improved. |
| VER-87964 | Tuple Mover | The Tuple Mover logged a large number of PURGE requests on a projection while another MERGEOUT job was running on the same projection. This issue has been resolved. |
Updated 06/22/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑86940 | Data Export, S3 | Export to Parquet sometimes logged errors in a DC table for successful exports. This issue has been resolved. |
| VER-87120 | Kafka Integration, Security | Previously, using a Kafka Notifier with SASL_SSL or SASL_PLAINTEXT would incorrectly use SSL instead. This issue has been resolved. |
| VER-87144 | Catalog Engine | Truncating a local temporary table unnecessarily required a global catalog lock, as temporary tables are session scoped. This issue has been resolved. |
| VER-87256 | Optimizer | Merge queries with an INTO...USING clause that calls a subquery would sometimes return an error when merging into a table with Set Using/Default query columns. The issue has been resolved. |
| VER-87259 | Execution Engine | Because the explode function is a 1:N transform function, using ORDER BY in its OVER clause has an undefined effect. Previously, using an ORDER BY clause in the OVER clause of Explode could result in an INTERNAL error if the configuration parameter TryPruneUnusedDataEdges was set to 1. This issue has been resolved. |
| VER-87295 | Optimizer | Queries eligible for TOPK projections that were also eligible for elimination of no-op joins would sometimes exit with internal error. The issue has been resolved. |
| VER-87434 | ComplexTypes | The flex and kafka parsers would erroneously not respect the parameter "reject_on_materialized_type_error" in cases where an array was too large for the target column, and no element was rejected. Previously, such values would always be rejected. This has been corrected, and now if "reject_on_materialized_type_error" is false, those values will be set to NULL instead. |
| VER-87443 | Data load / COPY | In some circumstances, Parquet file row groups whose metadata field "TotalBytes" has the value 0 might not load. This issue has been resolved. |
Updated 05/25/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑87099 | Execution Engine | When evaluating check constraints on tables with multiple projections with different sort orders, Vertica would sometimes read the data from the table incorrectly. This issue has been resolved. |
| VER-87103 | ComplexTypes | Previously, the flex table and Kafka parsers could crash if they tried to load array data that is too large for the target table. This behavior was fixed but introduced a change where those array values would cause the whole row to be rejected instead of setting the array value to NULL. Now, the default behavior is to set the data cell to NULL if the array value is too large. This can be overridden with the "reject_on_materialized_type_error" parameter, which will have the rows be rejected instead. |
Updated 04/25/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑86560 | FlexTable | In some cases COMPUTE_FLEXTABLE_KEYS used to assign non-string data types to keys where string data type was more suitable. The algorithm was improved to prefer string types in those cases. |
| VER-86651 | ComplexTypes | The flex JSON and Avro parsers did not always correctly handle excessively large ARRAY[VARCHAR] inputs. In certain cases this would lead to undefined behavior resulting in a crash. This issue has been resolved. |
Updated 04/25/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑85163 | Recovery | Recovery from scratch reset cpe to 0, but mergeout was disabled for the projection whose cpe was 0. This restriction has been removed to allow concurrent data loading. |
| VER-85649 | Database Designer Core | DESIGNER_DESIGN_PROJECTION_ENCODINGS returned with an error if a period was embedded in the design name. This issue has been resolved. |
| VER-86097 | Execution Engine | Predicate reordering optimization moved a comparison against a constant ahead of SIP filters, but the SIP filter needed to be evaluated after the constant predicate. This issue has been resolved: now, predicates are not reordered when a stateful SIP filter needs to be evaluated in a particular order. |
| VER-86130 | Optimizer | Queries with deeply nested expressions caused nodes to crash due to stack overflow. This issue has been resolved: now, the query runs normally if stack overflow occurs during non-essential stages of query processing–for example, getting pretty print for the expressions; or the query fails with an error message that the query contained an expression too large to analyze. |
| VER-86281 | Execution Engine | When pushing down predicates of a query that involved a WITH clause being turned into a shared temp relation, an IS NULL predicate on the preserved side of a left outer join was pushed below the join. As a result, rows that should have been filtered out were erroneously included in the result set. This issue has been resolved by updating the predicate pushdown logic. |
| VER-86317 | Optimizer | LIMIT k OVER (...) clauses incorrectedly estimated output rows by k, where k was calculated for every partition in the OVER clause. This issue has been resolved: estimation of output rows is now derived from the OVER clause. |
| VER-86319 | Recovery | When you applied a swap partition event to one table, the other table involved in the same swap partition event was removed from the dirty transactions list. This issue has been resolved. Now, both tables involved in the same swap partition event are in the dirty transaction list. |
| VER-86341 | AP-Geospatial | If you nested multiple geospatial functions when reading from a Parquet file, there was an issue finding usable memory that made the database crash. This issue has been resolved. |
| VER-86342 | Data load / COPY | A check to prevent TOCTOU (time of check to time of use) privilege escalations issued false positives in cases where a file is appended to during a COPY. This issue has been resolved: the check has been updated so it no longer issues a false positive in such situations. |
| VER-86347 | Admin Tools, Security | Paramiko has been upgraded to 2.10.1 to address CVE-2022-24302. |
Updated 03/10/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑85071 | UI - Management Console | Two MC Activity pages, Table Utilization and Table Details, erroneously referenced system table columns that were removed in an earlier release. This issue has been resolved. |
| VER-85385 | Data Export | Previously all exports to parquet/orc/delimited/JSON would fail if the exported query invoked a multi-part query plan. This has been fixed. |
| VER-85438 | Optimizer | Queries containing WITH statements with sorted output referenced in a different way throughout the query would sometimes return wrong results. The issue has been fixed. |
| VER-85439 | Admin Tools | Installation of an external procedure wrote the copied file in strings rather than bytes. Length calculation errors occurred when Japanse, Chinese, or other special characters were inserted, causing discrepancies between byte and string lengths. This issue has been resolved by writing the copied file in bytes. |
| VER-85493 | Tuple Mover | The Mergeout strata algorithm had a hidden overflow issue due to incorrect type casting for wide projections with more than 4095 columns. This issue has been resolved. |
| VER-85571 | Catalog Engine | Vertica 10.1 added support for bounds to array types. Addition of these bounds made changes to typemod, which represented column details such as VARCHAR length, and timestamp precision. The changes to typemod were not correctly accounted for in the metadata tables odbc_columns and jdbc_columns, which resulted in inconsistent TIMESTAMP column definitions. This issue has been resolved. |
| VER-85803 | Security | Patched libtar to protect against CVE-2021-33643, CVE-2021-33644, CVE-2021-33645, and CVE-2021-33646. |
| VER-85949 | Execution Engine | Previously, the NULLIF function would produce an error when given a volatile input (e.g. RANDOM() or user-defined aggregates). NULLIF now accepts any input. |
| VER-85950 | Security | Fixed an LDAP exception when the username of an LDAP user is modified manually in Vertica and conflicts with a new LDAP user, causing the initiator node to go down. |
Updated 02/02/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑85015 | Security | Enabling data-channel encryption with a self-signed certificate could cause the database to go down. This issue has been resolved. |
| VER-85237 | Security | The "starttls" LDAP authentication parameter is no longer deprecated and should generally be used when the LDAPAuth TLS Configuration is not granular enough to handle your environment. For example, if you have several LDAPAuth servers and only some of them can handle TLS, you should set (using ALTER AUTHENTICATION) "starttls" to "soft" in your authentication record to make TLS a preference and not a requirement. For details, see the Vertica documentation on LDAP authentication parameters. |
Updated 01/06/2023
| Issue Key | Component | Description |
|---|---|---|
| VER‑84838 | Optimizer | Queries with several subqueries in SELECT that were are also in the GROUP BY clause sometimes returned with an error. This issue has been resolved. |
Updated 12/06/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑84315 | Optimizer | If a query with an ORDER BY clause also contained a WITH clause with its own ORDER BY clause, and configuration EnableWITHTempRelReuseLimit=1, Vertica occasionally crashed in the late stages of query planning. This issue has been resolved. |
| VER‑84411 | Backup/DR | When vbr failed to launch vertica-download-file or vertica-download-file ended with error, vbr raised an error because it tried to load the error message as json. This issue has been resolved with more error handling. |
| VER‑84524 | Admin Tools | admintools uses a pseudoterminal (ssh + expect) to transfer data between nodes. When sending data larger than 4k, successful transfer depends on disabling canonical mode in the pseudoterminal. In some cases, this setting was ignored. This issue has been resolved. |
Updated 11/18/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑83921 | Optimizer | When UPDATE referenced a table column with an access policy, the access policy rule was applied twice instead of once. This issue has been resolved: now the access policy rule is applied only once. |
| VER‑84167 | Procedural Languages | Previously, running ANALYZE_STATISTICS through a stored procedure without superuser privileges could cause the database to go down. This has been fixed. |
| VER‑84170 | Data Export | Export to delimited did not allow the same character to be used for both 'escapeAs' and 'enclosedBy'. This restriction has been removed. |
| VER‑84173 | Control Networking | Previously, addition of standby nodes changed the assignment of control nodes and number of fault groups. This issue has been resolved: standby nodes are no longer set as control nodes. |
| VER‑84240 | Optimizer | Queries with string expressions in SELECT statements that were part of other expressions and also contained constant expressions sometimes returned an error. The issue has been resolved. |
| VER‑84244 | Backup/DR | The vbr listbackup task failed with an error when nodes in the configuration file's [mapping] section did not match the nodes in database. This issue has been resolved: listbackup now returns with a warning about nodes that are missing in the configuration file. |
Updated 11/07/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑84194 | Storage and Access Layer | If you added a column to a table in an Eon database with active subscribers to the shard of a DOWN node, Vertica failed to create storage containers for that column. As a result, attempts to query that column failed. This issue has been resolved: given the same conditions, Vertica now returns an error on attempts to add a table column. |
Updated 11/01/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑83547 | Catalog Engine | System table vs_storage_reference_counts was not updating the counter values in column num_accesses. This issue has been resolved. |
| VER‑83716 | Client Drivers - JDBC, Client Drivers - VSQL, Execution Engine | In the 12.0.0 release, the default values of Vertica KeepAlive parameters were non-NULL values, which overrode the equivalent kernel TCP keepalive parameters. This issue has been resolved: now, all Vertica KeepAlive parameters are set to 0 (NULL), so effective settings are obtained from TCP keepalive parameters. |
| VER‑83732 | UI - Management Console | timestamptz column microsecond values were truncated in MC. This issue has been resolved: database server timestamps with zone offset values are now properly represented. |
| VER‑83750 | Backup/DR | VBR uploads to S3 storage sometimes returned with error messages that the upload failed. This issue has been resolved: on receiving these messages, VBR now retries the upload operation. |
| VER‑83830 | Backup/DR | Previously, the vbr replicate task returned an error if the source and destination databases shared the same database name and IP addresses. This issue has been resolved: these restrictions no longer apply. |
| VER‑83858 | Backup/DR | Backup and restore on FIPS-enabled systems using object storage systems such as S3 could fail due to unavailability of the MD5 checksum implementation. These operations do not use MD5 for security, and this issue was resolved by flagging the uses of MD5 as not-for-security, thus enabling its use even with FIPS mode enabled. |
| VER‑83862 | Admin Tools | Recent Linux distributions such as RHEL 8 and Ubuntu 20 (and higher) introduced bracketed paste mode which, if enabled, broke intall_vertica and re_ip. This issue has been resolved. |
| VER‑83887 | Optimizer | Queries such as INSERT SELECT with reused WITH queries that had multipart DML query plans returned with errors when executed on an EON cluster with subclusters . This issue has been resolved. |
| VER‑83908 | Optimizer | Queries with complicated WITH clauses sometimes hung in Materialized WITH mode when directed queries or saved query plans were present in a database. The issue has been resolved. |
Updated 09/30/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑83194 | UI - Management Console | If a database with extended monitoring enabled went down, its Extended Monitoring page displayed no data. This issue has been resolved. |
| VER‑83376 | Machine Learning | Rounding errors in calculating the inclusive lower bound of tree-based algorithms caused unexpected behavior. This issue has been resolved. |
| VER‑83401 | Execution Engine | When processing the LAST_VALUE() function, the sort column was initialized using the input column's data type. In cases where the data types of the input and sort columns differed, Vertica used the wrong null representation. This issue has been resolved: now, the sort column is correctly initialized as per the ORDER BY column data type. |
| VER‑83433 | DDL | The REPLACE function occasionally produced a string that exceeded the maximum string length of 65000 octets, and returned with an error. This issue has been resolved: the function no longer creates a result string that exceeds 65000 octets. |
| VER‑83481 | Database Designer Core | When Database Designer processed queries that referenced non-table objects such as projections with pre-aggregated data, it sometimes failed or produced core dumps and database crashes. This issue has been resolved: now Database Designer skips queries of these types. |
| VER‑83484 | Security | In some cases, the LDAP Link service could fail to create users due circular assignment after the first synchronization. This issue has been resolved. |
| VER‑83486 | ComplexTypes, Optimizer | The parameter "TryPruneUnusedDataEdges" toggles an optimization which tries to identify data edges of a query plan which are not necessary to compute the final result. This optimization would raise an INTERNAL error in rare situations with queries that perform a network resegment. This issue has been resolved. |
Updated 09/14/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑83146 | Client Drivers - JDBC, Sessions | JDBC now properly runs PreparedStatement.execute() for insert statements with complex types. |
| VER‑83149 | EON, ResourceManager | Previously, altering the max size of resource pools for non-local subclusters sometimes returned an error. This issue has been resolved. |
| VER‑83306 | Kafka Integration | Under certain conditions, Vertica crashed when exporting data to Kafka. This issue has been resolved. |
| VER‑83399 | Execution Engine | In some queries with highly selective predicates, StorageMerge ran slower than expected, especially with higher CPU core counts. This issue has been resolved. |
Updated 08/30/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑82766 | Optimizer | Queries with complex WITH clauses that used materialized WITH were running out of memory at the parsing stage. This issue has been resolved. |
| VER‑82814 | Data Export, Data load / COPY, Hadoop | When reading partition values from file paths, values that contained a '/' character were being read incorrectly by Vertica. This issue has been resolved. |
| VER‑82849 | DDL - Table | After renaming a table with ALTER TABLE, the DDL for its projections continued to reference the previous name as an alias of the new name. This issue has been resolved: when a table is renamed, the DDL of its projections is also updated. |
| VER‑82865 | DDL | Some UNION ALL queries failed with the error 'Temp relation descriptor not provided.' This issue has been resolved. |
| VER‑82880 | DDL | Vertica allows any partition expression that resolves to non-NULL values, even in cases where the expression columns originally contained NULL values. Conversely, Vertica no longer allows a partition expression that produces NULL values even if the expression columns contain no NULL values. |
| VER‑82905 | Depot | If the depot had no space to download a new file, the data loading plan did not write the file to the depot. Instead, it viewed the file as already in the depot, and incorrectly returned an error that the file size did not match the catalog. This issue has been resolved: the data loading plan no longer regards the absent file as in the depot. |
| VER‑82941 | Client Drivers - JDBC | When JDBC connected to the server with BinaryTransfer and the JVM timezone had a historical or future Daylight Saving Time (DST) schedule, querying DST start dates in the JVM timezone sometimes returned incorrect data. This issue has been resolved; however, performance of BinaryTransfer for DATE data is worse than that of TextTransfer. |
| VER‑82968 | Data load / COPY | Flex table parsers did not reserve enough buffer space to correctly process certain inputs to NUMERIC-type columns. This issue has been resolved. |
| VER‑82981 | Execution Engine | Queries with multipart plans that produced large temporay relations sometimes failed to clean up temporary files. This issue has been resolved. |
| VER‑83052 | Cloud - Amazon, UI - Management Console | When a previously used IP address was repeated from the subnet, Management Console failed to add hosts to the cluster. This issue is now resolved. |
| VER‑83053 | Cloud - Amazon, UI - Management Console | After using Management Console to revive a database in the cloud, the database sometimes failed to start because of a lost+found directory in the catalog path. This issue is now resolved. |
| VER‑83070 | Admin Tools | pexpect inefficiently closed potential file descriptors when the nofile limit was high, attempting to close all file descriptors whether they were open or closed. This issue has been addressed: when the number of file descriptors is ≤2000, pexpect uses closerange to close the file descriptors, as it preforms better than close in a loop. When the the number of file descriptors >2000, pexpect iterates over the file descriptors in /proc/self/fd, which contains open file descriptors only, and closes them. |
| VER‑83071 | Optimizer | Queries with a UNION on EON subclusters resegmented grouped UNION leg outputs, even if UNION legs were segmented on group keys. This issue has been resolved, thereby improving query performance. |
| VER‑83088 | Backup/DR | vbr calls to the AWS function DeleteObjects() did not gracefully handle SlowDown errors. This issue has been resolved by changing the boto3 retry logic, so SlowDown errors are less likely to occur. |
Updated 08/03/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑82377 | Admin Tools | Adding two nodes to a one-node enterprise database required the database to be rebalanced and made K-safe. Attempts to rebalance and achieve K-safety on the admintool command line ended in an error, while attempts to update K-safety in the admintools GUI also failed. These issues have been resolved. |
| VER‑82380 | ComplexTypes, FlexTable | When parsing arrays of primitive types using the JSON parser, COPY failed with a message about records being too large. This issue has been resolved. |
| VER‑82381 | AP-Geospatial | In some cases, ST_GeomFromGeoJSON returned a non-null result on null input. This issue has been resolved. |
| VER‑82629 | Client Drivers - VSQL | The vsql client returned no error code if it encountered an error whle running a long query--for example, exceeding a resource pools's RUNTIMECAP setting. This issue has been resolved. |
| VER‑82635 | Optimizer | Previously, if a partition range projection included a column defined by an expression derived from another table column, querying on the projection sometimes caused the server to crash. This issue has been resolved. |
| VER‑82757 | ComplexTypes | The array_count function read all fields of a complex array from storage. Doing so resulted in high cost estimates and sub-optimal query plans. This issue has been resolved: array_count now reads only one field. |
| VER‑82758 | Execution Engine | The optimizer removes predicates from a query if expression analysis finds them to be true for entire storage containers. When the same predicate appeared multiple times in a given query, and one of those predicates passed expression analysis, sometimes the optimizer removed all instances of that predicate. This issue has been resolved: the optimizer no longer removes multiple instances of the same predicate when one of them passes expression analysis. |
| VER‑82759 | Execution Engine, Optimizer | If join output required sorting and was used by another merge join, but had multiple equivalent sort keys, the sort keys were not fully maintained. In this case, the query returned with incorrect results. This issue has been resolve by maintaining the necessary sort keys for merge join input. |
| VER‑82774 | Execution Engine | The makeutf8 function sometimes caused undefined behavior when given maximum-length inputs for the argument column type. This issue has been resolved. |
| VER‑82806 | Backup/DR | If you restored a backup to another database with a different communal storage location, startup on the target database failed if the database's oid was assigned to another object. This issue has been resolved. |
Updated 07/14/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑81807 | Catalog Engine | In a database with large number of projections, querying system table vs_segment or views of vs_segment sometimes returned with an error that the MaxParsedQuerySizeMB limit had been exceeded. This issue has been resolved. |
| VER‑82162 | Security | Previously, running LDAP_LINK_DRYRUN_SEARCH and LDAP_LINK_DRYRUN_SYNC without the optional parameter LDAPLinkJoinAttr caused the database to go down. This issue has been resolved. |
| VER‑82188 | Catalog Engine, DDL, UDX | Previously, CREATE PROCEDURE did not properly check for duplicate formal parameters in cases where parameter names differed only by case. This issue has been resolved. |
| VER‑82664 | Execution Engine | If the REPLACE function was called with an empty string as the replacement (third) argument, it always returned a single-character result. This issue has been resolved. |
Updated 06/16/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑81388 | Admin Tools | Attempts to replace a down node in the admintools GUI or on the command line by calling db_replace_node or restart_node with the --force option failed. This issue has been resolved. |
| VER‑82041 | Execution Engine | Addition of configuration parameter EnablePredicateRemoval introduced performance regressions in certain queries. This regression has been corrected. |
| VER‑82245 | Execution Engine | There was a performance issue when you executed a query on the VARBINARY(16) data type. This issue has been resolved. |
Updated 06/08/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑81738 | UI - Management Console | Some cookie features were not set properly in HTTP headers. This issue has been resolved. |
| VER‑81849 | Tuple Mover | Mergeout plans converted StorageMerge to StorageUnion+Sort, which slowed down mergeout and adversely affeced performance. This issue has been resolved: StorageMerge is no longer converrted to StorageUnion+Sort. |
| VER‑81852 | UI - Management Console | Management Console was unable to start a database if the URL for communal storage ended with a backslash ('/'). This issue has been resolved. |
| VER‑81913 | Execution Engine | Running analyze_statistics sometimes caused significant, unexpected slowdowns on concurrent queries. This slowdown was most noticeable on subsecond queries with StorageMerge operators in the plan. This issue has been resolved. |
| VER‑82036 | Execution Engine | Changed misleading counter name from "number of bytes read from communal storage" to "number of bytes read from persistent storage". |
| VER‑82038 | UI - Management Console | Version 5.1.6 of the Spring framework had a vulnerability that was resolved by updating to version 5.1.13. |
Updated 05/19/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑81388 | Admin Tools | Attempts to replace a down node in the admintools GUI or on the command line by calling db_replace_node or restart_node with the --force option failed. This issue has been resolved. |
| VER‑81871 | Security | Users synced from LDAP with an obsolete DN are orphaned. Previously, if you dropped these orphaned users and re-created them with LDAP Link, their roles were not preserved. This issue has been resolved: these types of users now retain their roles on re-creation with LDAP Link. |
Updated 05/3/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑53679 | Optimizer | Previously, live aggregate projections had difficulty rewriting AVG() if the argument was of type INT. This issue has been resolved. |
| VER‑62937 | Security | Previously, when configuring Kerberos authentication, not configuring the KerberosRealm parameter would cause the database to go down. This has been fixed; if KerberosRealm is not specified, Vertica automatically retrieves the realm from the Kerberos server and creates the connection. |
| VER‑65100 | Backup/DR | Running backup/restore on a cluster with non-permanent nodes led to a misleading failure. This issue has been resolved. |
| VER‑72363 | Backup/DR | Before this fix, the restored global catalog objects are installed on all the executor nodes after GCLX. The long process of catalog installation could cause GCLX timeout. This fix installs the restored global catalog objects on all the executor nodes before GCLX. |
| VER‑73776 | Optimizer | Adding a subcluster with a larger number of nodes to an EON cluster required an unexpectedly long amount of time. This issue has been resolved. |
| VER‑76092 | Data Networking | In rare circumstances, depending on the customer's network settings, TCP connections could still be considered alive for nodes that recently went down. That could result in significant query stalls or indefinite session hangs without ability to cancel. The issue has been resolved with improved TCP connection handling. |
| VER‑76948 | UI - Management Console | When an AWS cluster was scaled up, the MC did not load all data when a custom file system was detected, and the AWS key pair was not populated. These issues were resolved. |
| VER‑79025 | Data Removal - Delete, Purge, Partitioning, DDL - Table | In the past, an ALTER table's partition using an existing partition expression's internal representation was treated as a different partition expression and reorganized partition storage containers. Now, it is treated as the same partition expression and does not require partition storage container reorganization. |
| VER‑79357 | Optimizer |
The FROM clause of an UPDATE statement can now reference the target-table, as follows: FROM DEFAULT [join-type] JOIN dataset [ ON join-predicate ] DEFAULT specifies the table to update. This keyword can be used only once in the FROM clause, and it cannot be used elsewhere in the UPDATE statement. |
| VER‑80051 | Execution Engine | Vertica may crash after queries or DML operations with a storage merge. |
| VER‑80087 | Optimizer | Previously, DBD functions DESIGNER_ADD_DESIGN_QUERIES and DESIGNER_RUN_POPULATE_DESIGN_AND_DEPLOY only supported local file system locations as arguments. Now, they also support communal storage locations. |
| VER‑80359 | UI - Management Console | When creating a cluster, Management Console included unsupported characters in the key pair name when it generated the cluster IAM role name, which blocked the creation process. This issue has been resolved: now, MC removes unsupported characters in the key pair name from the generated IAM role name. |
| VER‑80361 | Execution Engine | Unlike a regular outer join, an event series join pads output with some cached values that represent the columns of the mismatched side. Padding with nulls is required if no previous rows are available for interpolation. To process event series joins, cached rows are always initialized with nulls, then updated with values to represent the mismatched side if applicable. When initializing cached rows with a schema that differed from what the join expected at that stage of the query plan, Vertica occasionally crashed. This issue has been resolved: now cached rows are initially set to null tuples, using the correct tuple schema. |
| VER‑80384 | UI - Management Console | When creating a cluster, Management Console included unsupported characters in the key pair name when it generated the cluster IAM role name, which blocked the cluster creation process. This issue has been resolved: now, MC removes unsupported characters in the key pair name from the generated IAM role name. |
| VER‑80416 | Client Drivers - JDBC, Execution Engine | Previously, when using the JDBC and ADO.net drivers with binary encoding, queries that contained NUMERIC literal expressions that used parameterized prepared statement queries--could have incorrect precision and scale. This issue has been resolved. |
| VER‑80441 | Backup/DR, Migration Tool | After migrating a database from Enterprise to Eon mode, loading data into tables with unsegmented projections could fail with the error "Cannot plan query because no super projections are safe". This issue has been resolved. |
| VER‑80496 | UDX | EDIT_DISTANCE allocates memory properly instead of using the limited stack memory which was causing crashes on very large strings. |
| VER‑80530 | Execution Engine | Vertica evaluates IN expressions in several ways, depending on the right-hand side. If the right-hand side is a subquery, then Vertica evaluates the expression as a join; if it is a list of constant expressions, then Vertica evaluates the expression by building a hash table of constant values; and if the expression is anything else, then Vertica either errors out, or evaluates the expression by rewriting it into a logical disjunction. Detection for the third case was flawed, resulting in an expression being evaluated incorrectly, which sometimes resulted in a crash. This issue has been resolved. |
| VER‑80537 | UI - Management Console | When you added an existing user to a Custom Threshold notification, the checkbox was not responsive. This issue was resolved |
| VER‑80551 | Control Networking | Depending on the customer's network settings, TCP connections were occasionally considered alive for nodes that recently went down. This could cause significant query stalls or indefinite session hangs without the ability to cancel. The issue has been resolved with improved TCP connection handling. |
| VER‑80552 | AP-Geospatial | STV_Create_Index can create incorrect indexes on large sets of polygons. Using these indexes might cause a query to fail or bring a node down. This issue has been resolved. |
| VER‑80553 | Execution Engine | The REPLACE function returned incorrect results if it called the SPLIT_PART function as its second (target string) argument. This issue has been resolved. |
| VER‑80568 | Data Collector | Setting an empty channel in SET_DATA_COLLECTOR_NOTIFY_POLICY is now disallowed. |
| VER‑80575 | Monitoring | The ros_count column in system view projection_storage was removed in release 11.0.2. This column has been restored, as per requests from clients who used it for monitoring purposes. |
| VER‑80637 | Execution Engine | As a performance optimization, Vertica analyzes whether expressions can be true or false over a range of values, to avoid evaluating that expression for each row in the range. The analysis function regexp_like() sometimes returned incorrect results when the regular expression contained characters that allowed a pattern to match zero times, such as "?" and "*". This issue has been resolved. |
| VER‑80655 | UI - Management Console | Previously, MC saved a DBD-generated design only when database K-safety was set to 0. This, issue has been resolved: now MC saves the design irrespective of the K-safety setting. |
| VER‑80697 | UI - Management Console | Before the introduction of custom threshold, email will be sent on "critical" and "alert" priority. After the introduction of custom threshold we let the users to send emails on all priorities. This change has been implemented on all Thresholds, but since "Node state change" is a different criteria, that changes are not in effect. Now we have changed "Node state change" threshold to send email on all alert priority. |
| VER‑80728 | Execution Engine | Partition-ranged projections did not work well with tables with Numeric typed partition expressions--for example, using the date_part function in the partition expression. This issue has been resolved. |
| VER‑80749 | Admin Tools | admintools -t re_ip options -T and -U did not update admintools.conf with the correct control messaging protocol. This issue has been resolved. |
| VER‑80765 | Admin Tools | The admintools operation db_add_node failed if the first node in the cluster was down. This failure occurred because after adding the node, db_add_node would try to use the first node as the source node for syncing vertica.conf and spread.conf files. This issue has been resolved: now, Vertica uses any UP node as the source node for syncing. |
| VER‑80823 | Client Drivers - Misc, Security |
Fixed an issue where some Kerberos configurations would become invalid after upgrading to Vertica 11.1.0-0. A side effect of this fix is that OAuth authentication records created in 11.1.0-0 become invalid when upgrading to 11.1.0-1 or later. To fix this, drop and recreate these invalid OAuth authentication records. |
| VER‑80859 | UDX | New system prerequisites have been added for compiling C++ user-defined extensions (UDXs). See "Setting up the C++ SDK" for more details. https://www.vertica.com/docs/11.1.x/HTML/Content/Authoring/ExtendingVertica/C++/C++SDK.htm |
| VER‑80879 | Data load / COPY | Operations over directories containing large numbers of external data files on object stores consumed more CPU than expected. This issue affected planning for external table queries, COPY statements, and license auditing. An algorithmic change reduced the amount of CPU time used to perform these operations. |
| VER‑80888 | Admin Tools | Attempts to run multiple databases on the same cluster failed, even though each database ran exclusively on a different set of nodes--for example, database A with nodes 1 through 5, database B on nodes 6 through 10. This issue has been resolved. |
| VER‑80929 | UI - Management Console | When the Management Console is installed on a Linux server, some files are created in the /tmp folder. If these files are removed, the MC database is not restored and clients lose data during an upgrade. This issue has been resolved: the MC database is now restored after an upgrade. |
| VER‑80982 | Backup/DR | Replication on an Eon mode database requires access to communal storage locations on the source and target clusters. Since the Vertica 11.0.x release, replication on a database that used MiniIO communal storage locations failed because local nodes did not map correctly to those locations. This issue has been resolved. |
| VER‑80997 | Backup/DR | When running Eon mode replication tasks, vbr returned with an error when it tried to connect to Vertica through a non-primary subscriber node. This issue has been resolved. |
| VER‑81035 | Catalog Engine | LDAPLink now holds the GCLX for less time when Vertica synchronizes users and groups from an LDAP server. |
| VER‑81055 | Optimizer | Previously, if two SELECT clause subqueries matched exactly, the subquery reuse feature created two different VARs instead of a single VAR for both, resulting in the GROUP BY expression being unable to find the relevant expression for the second VAR generated. This issue has now been fixed by generating a single VAR when the subqueries match exactly. |
| VER‑81063 | Scrutinize | Due to previous update on ATCommand method, the scrutinize functions are broken. This fix will resolve that issue. |
| VER‑81238 | Admin Tools | Administration Tools no longer kills all cluster nodes after the default timeout if some nodes are still initializaing. Also, if users do not respond to the timeout prompt, Administration Tools continues to wait. |
| VER‑81504 | Security | In order to mitigate CVE-2022-0778 we have upgraded the version of OpenSSL that we ship to 1.1.1n |
Updated 02/24/2022
| Issue Key | Component | Description |
|---|---|---|
| VER‑1596 | Client Drivers - JDBC, Sessions | Each Vertica node now uses TCP keepalive to detect if it is disconnected from and automatically free resources allocated for a client. |
| VER‑73125 | Recovery | The Tuple Mover uses the configuration parameter MaxMrgOutROSSizeMB to determine the maximum size of ROS containers that are candidates for mergeout. After a rebalance operation, Tuple Mover now groups ROS containers in batches that are smaller than MaxMrgOutROSSizeMB. A ROS container that is larger than MaxMrgOutROSSizeMB is merged individually. |
| VER‑77380 | Optimizer, Performance tests | Running analyze_statistics('') on a large catalog would sometimes run out of memory and (at best) fail or (at worst) trigger an "out of memory" in the kernel. This has been resolved. |
| VER‑79545 | DDL | Previously, you could not resize a table column that was used to segment any of that table's projections. This restriction has been lifted. Now, ALTER TABLE...ALTER COLUMN can modify the column's data type so it is larger or smaller than before, as long as the new size does not affect existing data. |
| VER‑79811 | Backup/DR | During backup, vbr sends queries to vsql and reads the results from each query. If the vsql output comprised multiple lines that ended with newline characters, vbr mistakenly interpreted the newline character to indicate the end of output from the current query and stopped reading. As a result, when vbr sent the next query to vsql, it read the unread output from the earlier query as belonging to the current query. This issue has been resolved: vbr now correctly detects the end of each query result and reads it accordingly. |
| VER‑79902 | Admin Tools | create_db failed in FIPS mode. This issue has been resolved. |
| VER‑79913 | DDL | Previously, IMPORT_STATISTICS was unable to import statistics from output generated by EXPORT_STATISTICS_PARTITION. This issue has been resolved. |
| VER‑80002 | Security | ALTER TLS CONFIGURATION data_channel now validates that the specified certificate can be used for internode encryption. |
| VER‑80038 | DDL, Execution Engine | The server crashed when system queries used large strings as predicate constants--for example, "table_name = ..." or "schema_name = ..." This issue has been resolved. |
| VER‑80049 | Kafka Integration, UI - Management Console | Security vulnerabilities CVE-2021-44228 and CVE-2021-45046 were found in earlier versions of the log4j library used by the MC. The library has been updated to resolve this issue. |
| VER‑80052 | UI - Management Console | This release updates the Management Console's Log4j library. The updated library addresses the CVE-2021-44228 and CVE-2021-45046 security vulnerabilities found in earlier versions. |
| VER‑80053 | Kafka Integration | This release updates the Kafka integration's Log4j library. The updated library addresses the CVE-2021-44228 and CVE-2021-45046 security vulnerabilities found in earlier versions. |
| VER‑80124 | Execution Engine | Certain queries with ill-formed predicates that contained a large number of fields caused Vertica to run out of memory while trying to return an error message. This issue has been resolved: now, Vertica can build and return error messages of the type operator-not-found, regardless of length. |
| VER‑80227 | ComplexTypes | A bug in the code caused parsing of nested case statements to become inefficient. This resulted in much larger processing time for case statements with multiple levels of nesting. This issue has been resolved: processing of nested case statements is again linear in the number of nesting levels. |
| VER‑80262 | Backup/DR | On LINUX_FILESYSTEM, when a snapshot was in progress, vertica called glob() on all storage containers and then called stat() to check container statistics. If an error occurred between these two operations, the backup operation failed. This issue has been resolved: on LINUX_FILESYSTEM, the snapshot now only calls stat() on storage containers. |
| VER‑80316 | ComplexTypes, Execution Engine | Previously, expressions with "subquery." as arguments (not in the top level of a SELECT statement or subquery) could result in undefined behavior. This issue has been resolved. Now, whenever "subquery." appears as an expression argument, it expands into a complex ROW expression with one field for each of the subquery's columns. |
| VER‑80388 | Execution Engine, UDX | As of 10.1, inline SQL functions could not be passed a volatile parameter if that parameter appeared multiple times in the function definition. As an inline function, RIGHT returned an error when it was called with a volatile user-defined aggregate function as its first parameter. This issue has been resolved: RIGHT is no longer an inline SQL function, and instead is now defined internally. |
| VER‑80439 | Kafka Integration | KafkaExport returns when it detects that all messages were sent to Kafka, reducing execution time up to 10 seconds. |
| VER‑80610 | Client Drivers - JDBC, Execution Engine | Previously, when using the JDBC and ADO.net drivers with binary encoding, queries that contained NUMERIC literal expressions that used parameterized prepared statement queries--for example, ?/10--could have incorrect precision and scale. This issue has been resolved. |
