Release v5.15.0 · Restream/reindexer

Core

[fea] Optimized ID-set intersection logic during queries. The new implementation adapts better to different ID distributions within sets
[fea] Added heap-based intersection for geo-queries with a large number of points. In certain scenarios, this can provide up to a 10x speedup (see the RStarRTreePointDWithin/1% benchmark)
[fea] Reduced the impact of background index optimization on write operations by increasing the granularity of optimization cancellation checks. Previously, background index optimization could trigger latency spikes for write operations
[fea] Made stack traces more informative for MUSL builds
[fea] Slightly optimized indexes memory layout under mixed write/read workloads
[fix] Fixed a bug with row invalidation in the joined cache
[fix] Added explicit error in case of fulltext index inside JOIN's ON clause. Previously those queries did not work correctly in the most of the cases

[fea] Added an optional streaming fetch for HNSW indexes. In this case, the query planner will rely on the query's final limit/offset instead of the k value

[fea] Added stricter checks for coroutine stack sizes
[fix] Fixed a rare issue where a RAFT cluster leader received a false error from Ping while another coroutine was handling an exception, causing it to fall back to the candidate role

[fea] Optimized encoding/decoding logic for binary structures related to queries and query results
[fix] Fixed NextObj and joined-fields oncorrect interactions: previously it could generate panic even on the correct data
