  • DigitalOcean Vector Databases is now generally available in Data Services that groups managed engines for vector similarity search. The launch includes:

    • Weaviate in private preview for retrieval-augmented generation and semantic search workloads. Available to opted-in customers; preview clusters are not billed.
    • OpenSearch with the k-NN, ML Commons, and Neural Search plugins for hybrid (vector plus keyword) search and remote embedding models. Uses the existing Managed Databases OpenSearch engine.
    • PostgreSQL with the vector (pgvector) and vectorscale (pgvectorscale) extensions for vector similarity search alongside relational data.

    For an overview and guidance on choosing an engine, see Vector Databases.

  • Storage autoscaling is now in general availability. Additionally, you can now reduce your cluster’s amount of additional storage, as long as the new storage size is greater than or equal to the latest backup’s size plus any data growth since then and a 25% buffer.

  • Now in public preview, you can now enable storage autoscaling on all Managed Database engines. To enable autoscaling, see our resizing guides for MySQL, PostgreSQL, MongoDB, OpenSearch, and Kafka.
