Databricks Apps telemetry is now generally available
Configuring telemetry for your Databricks apps is now generally available. Databricks Apps telemetry collects traces, logs, and metrics and persists them to Unity Catalog tables using the OpenTelemetry (OTel) protocol.
Lakebase Search is generally available
Lakebase Search is now generally available. It brings scalable vector and keyword search to Lakebase projects through two Postgres extensions, so you can run semantic and exact-term search in a single database without a separate search stack: lakebase_vector adds the lakebase_ann index type for approximate nearest-neighbor vector search.
