Enable parallel HASH join
When the parameter EnableAggressiveParallelJoins is enabled, it allows the query optimizer to consider parallel join strategies beyond the default conditions, potentially improving performance for join-heavy operations. While this can lead to significant runtime reductions, it may also increase resource consumption depending on workload characteristics and system configuration.
VectorOps UDx
VectorOps is now available as a default C++ UDx. You can use Vector functions to perform vector calculations, including vector magnitude, L2 distance, dot product, and cosine similarity.
Hadoop parameters
The WebhdfsUseCanonicalHost parameter controls the use of the canonical hostname during WebHDFS communication, including Kerberos authentication.
Configure environment variables in Kubernetes
You can add custom environment variables to the VerticaDB server and NMA container using extraEnv and envFrom fields. This supports secure management through Kubernetes Secrets and triggers automatic container updates when related ConfigMaps or Secrets change.
Promote or demote a subcluster in Kubernetes
You can now promote or demote a subcluster either in the main cluster or sandbox to either primary or secondary based on your workload.
Automatically rotate TLS certificates in Kubernetes with rollback support
You can now automatically rotate both httpsNMATLS and clientServerTLS certificates by providing a list of secrets and specifying a rotation interval. If rotation fails, VerticaDB automatically rolls back to the last successfully applied certificate when the annotation vertica.com/enable-tls-rotation-failure-rollback is set to true.
Integrated monitoring and logging support in Kubernetes
The VerticaDB Operator now includes built-in monitoring and logging with Prometheus, Grafana, Loki, and Alloy, providing end-to-end observability. You can now monitor metrics, visualize dashboards, collect logs, and set alerts directly through Grafana with minimal setup using Helm chart parameters.
Health Watchdog in the VCluster UI
Health Watchdog has been incorporated into the VCluster UI, allowing you to view the database health, tune health metrics, and view blocked transactions.
