AI Summary

This release focuses on performance optimizations such as deferred point updates and non-blocking Gridstore flushes to reduce search tail latencies. It includes critical bug fixes for WAL (Write-Ahead Log) operations and panics, as well as a security patch for snapshot recovery.

Key Highlights

  • Performance: Defer point updates efficiently with `prevent_unoptimized=true`
  • Performance: Non-blocking Gridstore flushes to reduce search tail latencies
  • Bug Fixes: Multiple fixes for WAL reading, replay, and delta transfer issues
  • Security: Force snapshot recovery from snapshot directory only
  • Preview: Per-collection metrics in Prometheus available in build

New Features

  • API for reading audit log entries (Preview)
  • Maximum batch size config in strict mode (Preview)
  • Feature flag: `prevent_unoptimized=true`
