Built for RAG and Agent

Hybrid Search on a Flexible Document Model

Perform multi-field vector search across text and images simultaneously — without flattening your schema.
Store vectors, keywords, text, and complex nested objects in a single document, and search your data exactly as it is.

query = { "rrf": [ # Keyword search on raw text {"queryString": {"query": user_query, "defaultField": "text"}}, # Semantic search on text embeddings {"knn": {"field": "text_vector", "queryVector": q_vec, "k": 5}}, # Semantic search on image embeddings {"knn": {"field": "image_vector", "queryVector": q_vec, "k": 5}} ] } results = lambda_db.collections.query( collection_name="assets", query=query )

Serverless Elasticity for Agent Storms

Compute, memory, and storage scale independently — with automatic shard scaling. No manual sharding. No capacity planning.
Whether it’s a single RAG query or a swarm of recursive agents, our disaggregated architecture instantly adapts using virtual sharding to maintain stable performance. Your ingestion pipeline never blocks your search.

Zero-Waste Scoped Retrieval

Don't search the whole library to find a single page. Retrieve only specific partitions based on tenant or category. Pay only for what you read, not for idle infrastructure.

Deploy 30+ regions worldwide

Deploy anywhere your service runs.
Your data stays where your users are.

Git-like Branching for your collection data

Tame data entropy. Fork your production index in seconds to test new embedding models or hybrid weights. Apply to production only when validated.
