General news


  • Intelligent build-to-build comparison
  • Compaction tests enhancements
  • Specification/description of performance tests




improvements


  • 2-3x faster initial indexing (non-DGM/DGM)
  • 3x  faster incremental indexing (non-DGM/DGM)
  • 2x lower query latency (stale=false)
  • 2-3x faster rebalance with views
  • 2x  faster KV rebalance out/swap

Regression


  • MB-10273: View compaction doesn't catch up in basic non-DGM tests with view queries
  • MB-10301: Major drops (up to 30%) in ops/sec in write-heavy performance test
  • MB-10302: Bucket compaction doesn't catch up causing higher disk usage in write-heavy tests

NOT REPORTED REGRESSION


  • Higher memory overhead due to UPR (waiting for MB-9897)

STILL NOT CLOSED


  • MB-10259: Constant ep-engine crashes during load phase
  • MB-10250: Higher memory fragmentation in append only workloads
  • MB-10164 :  Warmup is 1.5 slower in recent 3.0 builds
  • MB-10162 :  Views produce empty index during workload with ongoing mutations/indexing
  • MB-10167 :  20-25% higher beam.smp memory utilization in cases with views (2.5 vs 3.0)
  • MB-10192:  ep-engine crashed when reading data through TAP
