NUMA multi-node cluster management with VCluster CLI

VCluster CLI now supports managing NUMA (Non-Uniform Memory Access) multi-node clusters, where multiple database nodes run on the same physical host on different client ports. New options for add_node and remove_node let you specify per-node client ports and control NUMA node assignment for each host. This works both on real NUMA hardware and in standard environments running multiple nodes on a single host. For more information, see NUMA multi-node clusters.

3 - New and changed in version 26.2

New features and changes in version 26.2

Support multiple JWT public keys and optional JWK endpoint

Vertica now supports additional key sources for JWT token validation in OAuth authentication records. Two new parameters have been added:

  • jwt_ec_public_key: An EC (Elliptic Curve) public key, equivalent to the existing jwt_rsa_public_key parameter but for EC keys.
  • jwt_jwks_url: A URL pointing to the identity provider's JWK endpoint. The database automatically retrieves signing keys from this endpoint, eliminating the need to manually update keys during identity provider key rotation.

With these changes, jwt_rsa_public_key is no longer required. At least one of jwt_rsa_public_key, jwt_ec_public_key, or jwt_jwks_url must be set for a JWT authentication record to be active. You can configure any combination of these parameters.

See OAuth authentication parameters for more information.

Init containers for VerticaDB on Kubernetes

Run pre-start initialization tasks using init containers in the VerticaDB custom resource. You can now define containers that execute sequentially before the database server starts to prepare dependencies and validate the environment. For more information, see VerticaDB custom resource definition.

VerticaRestorePointsQuery custom resource

Manage database restore points using the VerticaRestorePointsQuery custom resource. You can now save, view, and restore from restore points. You can also alter or drop archives. For more information, see VerticaRestorePointsQuery custom resource definition.

Iceberg namespace support

Support is added for Apache Iceberg namespaces, enabling namespace management through CREATE ICEBERG NAMESPACE, ALTER ICEBERG NAMESPACE, and DROP NAMESPACE statements. Iceberg namespace metadata is available in the V_CATALOG system tables.

Automatic unsegmentation for non-superprojection tables

OpenText™ Analytics Database can automatically create unsegmented projections for tables that are created without a superprojection when they are first populated using a COPY operation with small source files. This behavior improves performance for small tables by eliminating the overhead of distributed processing. For more information, see Unsegmented projections.

Export to Iceberg tables

OpenText™ Analytics Database supports exporting to Iceberg tables that are managed directly by a filesystem, AWS Glue, or Hive metastore. This behavior is controlled by the IcebergCatalog parameter in the EXPORT TO PARQUET command.

MCP Server enhancements

Query profiling

Analyze SQL query performance using LLM-powered analysis of execution plans and runtime metrics. Capture and store query profiles, visualize plan trees, and export profile data for troubleshooting and optimization. For more information, see Query profiling.

VCluster database operations and health watchdog

All tools available in the VCluster server are also available through the MCP server. Perform VCluster database operations through the MCP server, including cluster management and health monitoring. The health watchdog continuously tracks cluster performance, node availability, and system health, providing real-time insights for proactive monitoring and alerting. For more information, see Database management with VCluster UI.

VCluster UI query profile page

Import and analyze query profile data directly from the VCluster UI. Specify a target schema and optional Key ID to organize profiles, then use integrated profiling tools to investigate performance, identify bottlenecks, and optimize queries. For more information, see Query Profile.
