  • Remove hard requirement of BASE64 encoding for binary field.
  • Add complexity limitation for GraphQL query to avoid malicious query.
  • Add Column.shardingKeyIdx for column definition for BanyanDB.
Sharding key is used to group time series data per metric of one entity in one place (same sharding and/or same
row for column-oriented database).
For example,
ServiceA's traffic gauge, service call per minute, includes following timestamp values, then it should be sharded by service ID
[ServiceA(encoded ID): 01-28 18:30 values-1, 01-28 18:31 values-2, 01-28 18:32 values-3, 01-28 18:32 values-4]

BanyanDB is the 1st storage implementation supporting this. It would make continuous time series metrics stored closely and compressed better.

NOTICE, this sharding concept is NOT just for splitting data into different database instances or physical files.
  • Support ElasticSearch template mappings properties parameters and _source update.

  • Trim tag's key and value in log query.
  • Refactor IoTDB storage plugin, add IoTDBDataConverter and fix ModifyCollectionInEnhancedForLoop bug.
  • Bump up iotdb-session to 0.12.5.
  • Fix the configuration of Aggregation and GC Count metrics for oap self observability
  • E2E: Add verify OAP eBPF Profiling.
  • Let multiGet could query without tag value in the InfluxDB storage plugin.
  • Adjust MAL for V9, remove some groups, add a new Service function for the custom delimiter.
  • Add service catalog DatabaseSlowStatement.
  • Add Error Prone Annotations dependency to suppress warnings, which are not errors.

UI

  • [Breaking Change] UI Templates have been redesigned totally. GraphQL query is minimal compatible for metadata and metrics query.
  • Remove unused jars (log4j-api.jar) in classpath.
