QUERY_CONSUMPTION
Summarizes execution of individual queries.
Summarizes execution of individual queries. Columns STATEMENT_ID and TRANSACTION_ID combine as unique keys to these queries. One exception applies: a query with multiple plans has as many records.
| Column Name | Data Type | Description |
|---|---|---|
START_TIME END_TIME |
TIMESTAMP | Demarcate the start and end of query execution, whether successful or not. |
SESSION_ID |
VARCHAR | Identifies the session where profiling information was captured. This identifier is unique within the cluster at any point in time, but can be reused when the session closes. |
USER_ID |
INTEGER | Unique numeric user identifier assigned by the Vertica catalog. |
USER_NAME |
VARCHAR | User name specified by this query profile. |
TRANSACTION_ID |
INTEGER | Identifies the transaction in which the query ran. |
STATEMENT_ID |
INTEGER | Numeric identifier of this query, unique within the query transaction. |
CPU_CYCLES_US |
INTEGER | Sum, in microseconds, of CPU cycles spent by all threads to process this query. |
NETWORK_BYTES_SENT NETWORK_BYTES_RECEIVED |
INTEGER | Total amount of data sent/received over the network by execution engine operators. |
DATA_BYTES_READ DATA_BYTES_WRITTEN |
INTEGER | Total amount of data read/written by storage operators from and to disk, includes all locations: local, HDFS, S3. |
DATA_BYTES_LOADED |
INTEGER | Total amount of data loaded from external sources: COPY, external tables, and data load. |
BYTES_SPILLED |
INTEGER | Total amount of data spilled to disk—for example, by SortManager, Join, and NetworkSend operators. |
INPUT_ROWS |
INTEGER | Number of unfiltered input rows from DataSource and Load operators. INPUT_ROWS shows the number of input rows that the query plan worked with, but excludes intermediate processing. For example, INPUT_ROWS excludes how many times SortManager spilled and read the same row. |
INPUT_ROWS_PROCESSED |
INTEGER | Value of INPUT_ROWS minus what was filtered by applying query predicates (valindex) and SIPs, and rows rejected by COPY. |
PEAK_MEMORY_KB |
INTEGER | Peak memory reserved by the resource manager for this query. |
THREAD_COUNT |
INTEGER | Maximum number of threads opened to process this query. |
DURATION_MS |
INTEGER | Total wall clock time, in milliseconds, spent to process this query. |
RESOURCE_POOL |
VARCHAR | Name of the resource pool where the query was executed. |
OUTPUT_ROWS |
INTEGER | Number of rows output to the client. |
REQUEST_TYPE |
VARCHAR | Type of query—for example, QUERY or DDL. |
LABEL |
VARCHAR | Label included as a LABEL hint in this query. |
IS_RETRY |
BOOLEAN | This query was tried earlier. |
SUCCESS |
BOOLEAN | This query executed successfully. |
