Vector database

Redis Vector

Redis Vector Search extends Redis with vector similarity queries alongside familiar key, JSON, and search capabilities—useful when you already run Redis for caching or features and want co-located embeddings with low-latency hybrid retrieval without adding a separate database cluster.

Key insights

Concrete technical or product signals.

  • Best when Redis is already in the critical path and you want vectors next to application state for sub-10ms-class patterns where feasible.
  • Capacity planning must include RAM footprint for vectors plus eviction policies—vectors are not free versus pure cache keys.

Use cases

Where this shines in production.

  • Real-time personalization with embeddings beside session state
  • Smaller RAG footprints that fit in Redis memory with replication
  • Gradual vector adoption without introducing a new datastore category

Limitations & trade-offs

What to watch for.

  • Not every Redis deployment tier exposes the same vector limits—check enterprise vs OSS feature matrix.
  • Very large embedding corpora may still warrant a dedicated vector engine—benchmark at target scale.
