Pluggable Index Abstraction With Runtime Index Selection

Scalable vector database — billion-scale, GPU acceleration, multiple index types, Zilliz Cloud.

Unique: IndexNode abstraction decouples index implementation from query execution; supports building multiple indexes in parallel without blocking ingestion, unlike competitors that require exclusive index lock during build

vs others: More flexible than Weaviate's fixed index selection and faster index building than Qdrant due to parallel IndexNode workers
