Raw Blame History

9.1.0

Project

  • 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

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.
