The integration between AlloyDB for PostgreSQL and Knowledge Catalog (in Preview) is now enabled by default for all new AlloyDB clusters

## Feature Feature The integration between AlloyDB for PostgreSQL and Knowledge Catalog (in [Preview](https://cloud.google.com/products#product-launch-stages)) is now enabled by default for all new AlloyDB clusters. This integration provides a unified view of your metadata to simplify data governance and analysis. Recent enhancements feature near real-time synchronization, with updates reflecting in Knowledge Catalog within minutes, as well as expanded metadata details that now include Primary Keys and Foreign Keys. For more information, see [Integrate AlloyDB for PostgreSQL with Knowledge Catalog](https://cloud.google.com/alloydb/docs/knowledge-catalog-integration). ## Feature Feature You can now use the AlloyDB columnar engine to act as a read-optimized, in-memory cache for HNSW indexes. This increases the number of queries per second (QPS) that your database can handle for vector search workloads. This feature is available in[Preview](https://cloud.google.com/products#product-launch-stages).
