Features

  • Remove Bloom filter for dictionary-encoded tags.
  • Implement BanyanDB MCP.
  • Support deleting non-entity tags when updating the schema.
  • Remove check requiring tags in criteria to be present in projection.
  • Add sorted query support for the Property.
  • Update bydbQL to add sorted query support for the Property.
  • Remove the windows arch for binary and docker image.
  • Support writing data with specifications.
  • Persist series metadata in liaison queue for measure, stream and trace models.
  • Update the dump tool to support analyzing the parts with smeta files.
  • Add replication integration test for measure.
  • Activate the property repair mechanism by default.
  • Add snapshot time retention policy to ensure the snapshot only can be deleted after the configured minimum age(time).
  • Breaking Change: Change the data storage path structure for property model:
    • From: <data-dir>/property/data/shard-<id>/...
    • To: <data-dir>/property/data/<group>/shard-<id>/...
  • Add a generic snapshot coordination package for atomic snapshot transitions across trace and sidx.
  • Support map-reduce aggregation for measure queries: map phase (partial aggregation on data nodes) and reduce phase (final aggregation on liaison).
  • Add eBPF-based KTM I/O monitor for FODC agent.
  • Support relative paths in configuration.
  • Support ’none’ node discovery and make it the default.
  • Support server-side element ID generation for stream writes when clients omit element_id.
  • Implement entire group deletion.

Bug Fixes

  • Fix the wrong retention setting of each measure/stream/trace.
  • Fix server got panic when create/update property with high dist usage.
  • Fix incorrect key range update in sidx part metadata.
  • Fix panic in measure block merger when merging blocks with overlapping timestamps.
  • Fix unsupported empty string tag bug.
  • Fix duplicate elements in stream query results by implementing element ID-based deduplication across scan, merge, and result building stages.
  • Fix data written to the wrong shard and related stream queries.
  • Fix the lifecycle panic when the trace has no sidx.
  • Fix panic in sidx merge and flush operations when part counts don’t match expectations.
  • Fix trace queries with range conditions on the same tag (e.g., duration) combined with ORDER BY by deduplicating tag names when merging logical expression branches.
  • Fix sidx tag filter range check returning inverted skip decision and use correct int64 encoding for block min/max.
  • Ignore take snapshot when no data.
  • Fix measure standalone write handler resetting accumulated groups on error, which dropped all successfully processed events in the batch.
  • Fix memory part reference leak in mustAddMemPart when tsTable loop closes.
  • Fix memory part leak in syncPartContext Close and prevent double-release in FinishSync.
  • Fix segment reference leaks in measure/stream/trace queries and ensure chunked sync sessions close part contexts correctly.
  • Fix duplicate query execution in distributed measure Agg+TopN queries by enabling push-down aggregation, removing the wasteful double-query pattern.
  • Fix nil pointer panic in segment collectMetrics during shutdown.
  • Fix entity tag handling in trace filter to prevent TagIdx index mismatch when filtering with both entity and non-entity tags.

Document

Chores
