Vector Similarity Search Foundation For Retrieval Systems

via “vector similarity search with multiple indexing algorithms”

A query and indexing engine for Redis, providing secondary indexing, full-text search, vector similarity search and aggregations.

Unique: Supports three distinct ANN algorithms (FLAT, HNSW, SVS) selectable per index, with HNSW using hierarchical graph structure for logarithmic query complexity; integrates vector search directly into Redis' command protocol via FT.SEARCH with VECTOR clause, eliminating separate vector DB round-trips

vs others: Faster than Pinecone/Weaviate for sub-million-vector workloads because vectors live in the same Redis instance as source data, eliminating network latency; more operationally simple than Milvus because it's a single Redis module with no separate infrastructure
