    iotdb java 0.12.5, thrift 0.14.1, moshi 1.5.0, msgpack 0.8.16 dependencies. Remove InfluxDB and IoTDB relative codes
    and E2E tests.
  • Upgrade OAP dependencies zipkin to 2.23.16, H2 to 2.1.212, Apache Freemarker to 2.3.31, gRPC-java 1.46.0, netty to
  • Upgrade Webapp dependencies, spring-cloud-dependencies to 2021.0.2, logback-classic to 1.2.11

    and SHOULD NOT be used in production cluster.

OAP Server

    init-mode. This problem caused the OAP server to fail to start when the OAP server was down for more than a day.
  • Support autocomplete tags in traces query.
  • [Breaking Change] Replace all configurations **_JETTY_** to **_REST_**.

  • Add TiDB, OpenSearch, Postgres storage optional to Trace and eBPF Profiling E2E testing.
  • Add OFF CPU eBPF Profiling E2E Testing.
  • Fix searchableTag as rpc.status_code and http.status_code. status_code had been removed.
  • Fix scroll query failure exception.
