What's Changed

Stability, Consistency & Data Integrity

• Metadata Server Reliability: The replicated metadata server now ensures the latest NodesConfiguration is effectively tracked and used.
• Bifrost Log Chain Resilience: Multiple enhancements to Bifrost components improve log chain consistency:
  • Eager chain sealing on find_tail when consistency is required.
  • Clear diagnostics on why chain markers are created.
  • Automatic sealing of read streams upon detection of partial seals.
  • Watchdog-driven management of LogChainExtender, plus unified chain operations via LogChainWriter and a configurable read batch limit.
• Crash Safety: On panic, RocksDB’s WAL is guaranteed to be flushed, minimizing data loss risk.

Operational Hygiene & Reliability

• Worker Task Cleanup: Streamlined task management removes stale processes and avoids unintended pinning of the partition store manager.
• Snapshotting Improvements: Partition snapshot tasks are now smoother and more efficient.
• Ingress Runtime Simplification: Removed dedicated ingress runtime to simplify deployment architecture.
• Histogram & Metrics Tweaks:
  • Idle histogram timeouts disabled by default.
  • Configuration option for histogram timeout removed entirely.
  • Reduced metrics cardinality, benchmarked to debug builds only.
• Test Stability: Auto-improvement features are disabled in replicated-loglet integration tests for more predictable outcomes.
• Fix in Cluster State Logic: Corrected an issue where failing-over nodes could be falsely marked as alive.
• Config Reload Enhancements: Live updates after config reload now correctly reflect in applied DB settings.

Ecosystem & Interface Updates

• Observability Improvements: The object store now emits richer telemetry, helping operators better monitor key storage operations.
• CLI Enhancements: Added "single-address mode" to restatectl for more flexible node targeting.
• Admin/API UX Tweaks:
  • Workflow retention now correctly reflects in Admin API.
  • Added completion_retention and journal_retention fields to the SQL interface.
• Restate UI Refresh: Updated UI to versions v0.0.93 and v0.0.94 for interface polish. Plus, users are now prompted to choose where example assets are downloaded.
• SDK Telemetry: The Admin API now captures and reports information about used SDKs.
