Qdrant 1.14 - Reranking Support & Extensive Resource Optimizations - Qdrant

What this post added

Introduced a Score-Boosting Reranker that allows combining vector similarity with custom logic based on payload data (e.g., prioritizing titles, boosting recent results via datetime, factoring in geographical proximity using gauss_decay). Implemented Incremental HNSW Indexing to extend existing graphs instead of rebuilding them. Optimized batch query processing by splitting large batches into chunks for concurrent execution across threads. Improved resource utilization during segment optimization by saturating CPU and disk IO more effectively. Reduced memory usage in immutable segments.
