Qdrant 1.12 - Distance Matrix, Facet Counting & On-Disk Indexing - Qdrant

Qdrant 1.12 introduces the Distance Matrix API for calculating pairwise vector distances, enabling clustering and dimensionality reduction use cases. It also adds a Facet API for counting and aggregating unique values in payload fields, similar to SQL's GROUP BY. New on-disk support for text and geo indexes reduces memory footprint by storing index data on disk, with performance considerations for cold query latency and memory vs. disk trade-offs. The Distance Matrix API is also integrated into the Web UI's Graph Exploration Tool.
