Qdrant 1.16 - Tiered Multitenancy & Disk-Efficient Vector Search - Qdrant

What this post added

Introduced ACORN, a new search algorithm for filtered vector search that improves accuracy with multiple low-selectivity filters by exploring second-hop neighbors in the HNSW graph. Implemented Inline Storage for HNSW index, enabling disk-efficient vector search by storing quantized vector data directly within HNSW nodes. Enhanced full-text search with `text_any` condition and ASCII folding. Introduced Tiered Multitenancy, combining payload-based and shard-based multitenancy with tenant promotion from a fallback shard to dedicated shards.
