Project

• [IMPORTANT] Remove InfluxDB 1.x and Apache IoTDB 0.X as storage options, check details
  at here. Remove converter-moshi 2.5.0, influx-java 2.15,
  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
  4.1.76.
• Upgrade Webapp dependencies, spring-cloud-dependencies to 2021.0.2, logback-classic to 1.2.11
• [IMPORTANT] Add BanyanDB storage implementation. Notice BanyanDB is currently under active development
  and SHOULD NOT be used in production cluster.

OAP Server

• Add component definition(ID=127) for Apache ShenYu (incubating).
• Fix Zipkin receiver: Decode spans error, missing Layer for V9 and wrong time bucket for generate Service and
  Endpoint.
• [Refactor] Move SQLDatabase(H2/MySQL/PostgreSQL), ElasticSearch and BanyanDB specific configurations out of column.
• Support BanyanDB global index for entities. Log and Segment record entities declare this new feature.
• Remove unnecessary analyzer settings in columns of templates. Many were added due to analyzer's default value.
• Simplify the Kafka Fetch configuration in cluster mode.
• [Breaking Change] Update the eBPF Profiling task to the service level, please delete
  index/table: ebpf_profiling_task, process_traffic.
• Fix event can't split service ID into 2 parts.
• Fix OAP Self-Observability metric GC Time calculation.
• Set SW_QUERY_MAX_QUERY_COMPLEXITY default value to 1000
• Webapp module (for UI) enabled compression.
• [Breaking Change] Add layer field to event, report an event without layer is not allowed.
• Fix ES flush thread stops when flush schedule task throws exception, such as ElasticSearch flush failed.
• Fix ES BulkProcessor in BatchProcessEsDAO was initialized multiple times and created multiple ES flush schedule tasks.
• HTTPServer support the handler register with allowed HTTP methods.
• [Critical] Revert Enhance DataCarrier#MultipleChannelsConsumer to add
  priority to avoid consuming issues.
• Fix the problem that some configurations (such as group.id) did not take effect due to the override order when using
  the kafkaConsumerConfig property to extend the configuration in Kafka Fetcher.
• Remove build time from the OAP version.
• Add data-generator module to run OAP in testing mode, generating mock data for testing.
• Support receive Kubernetes processes from gRPC protocol.
• Fix the problem that es index(TimeSeriesTable, eg. endpoint_traffic, alarm_record) didn't create even after rerun with
  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 the support eBPF profiling field into the process entity.
• E2E: fix log test miss verify LAL and metrics.
• Enhance Converter mechanism in kernel level to make BanyanDB native feature more effective.
• Add TermsAggregation properties collect_mode and execution_hint.
• Add "execution_hint": "map", "collect_mode": "breadth_first" for aggregation and topology query to improve 5-10x
  performance.
• Clean up scroll contexts after used.
• Support autocomplete tags in logs query.
• Enhance Deprecated MetricQuery(v1) getValues querying to asynchronous concurrency query
• Fix the pod match error when the service has multiple selector in kubernetes environment.
• VM monitoring adapts the 0.50.0 of the opentelemetry-collector.
• Add Envoy internal cost metrics.
• Remove Layer concept from ServiceInstance.
• Remove unnecessary onCompleted on gRPC onError callback.
• Remove Layer concept form Process.
• Update to list all eBPF profiling schedulers without duration.
• Storage(ElasticSearch): add search options to tolerate inexisting indices.
• Fix the problem that MQ has the wrong Layer type.
• Fix NoneStream model has wrong downsampling(was Second, should be Minute).
• SQL Database: provide @SQLDatabase.AdditionalEntity to support create additional tables from a model.
• [Breaking Change] SQL Database: remove SQL Database config maxSizeOfArrayColumn and numOfSearchableValuesPerTag.
• [Breaking Change] SQL Database: move Tags list from Segment,Logs,Alarms to their additional table.
• [Breaking Change] Remove total field in Trace, Log, Event, Browser log, and alarm list query.
• Support OFF_CPU eBPF Profiling.
• Fix SumAggregationBuilder#build should use the SumAggregation rather than MaxAggregation.
• 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.
• Add profileDataQueryBatchSize config in Elasticsearch Storage.
• Add APIs to query Pod log on demand.
• Remove OAL for events.
• Simplify the format index name logical in ES storage.
• Add instance properties extractor in MAL.
• Support Zipkin traces collect and zipkin traces query API.
• [Breaking Change] Zipkin receiver mechanism changes and traces do not stream into OAP Segment anymore.

UI

• General service instance: move Thread Pool from JVM to Overview, fix JVM GC Count calculation.
• Add Apache ShenYu (incubating) component LOGO.
