πŸ›‘ Breaking changes πŸ›‘

  • exporterhelper: Reduce the default queue size to 1000 from 5000 (#7359) Affects any exporter which enables the queue by default and doesn't set its own default size. For example: otlphttp.

πŸ’‘ Enhancements πŸ’‘

  • exporter: Allow configuration of fields, RandomizationFactor and Multiplier, for exponential backoff algorithm when retry on failure is enabled (#6610)

  • connectors: Add "connectors", a new type of pipeline component (#2336)

    • Connectors connect pipelines by acting as an exporter in one or more pipelines and simultaneously as a receiver of corresponding data in one or more other pipelines. For example:
      • The forward connector can export data to another pipeline of the same type. This allows you to merge data from multiple pipelines onto a common pipeline. Or, you can replicate data onto multiple pipelines so that it may be processed in different ways and/or exported to different backends.
      • The count connector can count data of any type. Regardless of the type of data that is counted, it emits counts as metrics onto a metrics pipeline.
    • Connectors are currently disabled by default but can be enabled with the service.connectors feature gate.
    • See the connectors README for more details on how to use connectors.
  • service: Enable new pipelines implementation using graphs. Controlled by the service.graph featuregate. (#2336)

  • builder: added ldflags command option (#6940)

  • proctelemetry: Instrument proctelemetry.ProcessMetrics metrics with otel-go (#6886)

  • logging: Fix the attribute key used to identify the receiver data type in logging configuration (#7033)
