The alloydb_scann extension is updated to include the following vector search improvements. These features are generally available (GA):

• By default, new ScaNN vector index builds are automatically tuned. Manually-tuned indexes can be converted to automatically-tuned indexes. For more information, see Create a ScaNN index. • You can now automatically maintain your ScaNN vector indexes. AlloyDB incrementally manages your index such that when your dataset grows, AlloyDB updates centroids and splits large outlier partitions to provide better QPS and search results. For more information, see Maintain indexes automatically.
