open-telemetry/opentelemetry-java v1.3.0

Version 1.3.0

on GitHub

Changelog:

API

Enhancements

• Parsing of the W3C Baggage header has been optimized.

SDK

Behavioral Changes

• The implementation of SpanBuilder will no longer throw exceptions when null parameters are passed in. Instead,
  it will treat these calls as no-ops.

Enhancements

• Memory usage of the Tracing SDK has been greatly reduced when exporting via the OTLP or Jaeger exporters.
• The OTLP protobuf version has been updated to v0.9.0

Extensions

• A new experimental extension module has been added to provide a truly no-op implementation of the API. This
  is published under the io.opentelemetry.extension.noopapi name.
• The io.opentelemetry.sdk.autoconfigure module now supports the OTEL_SERVICE_NAME/otel.service.name
  environment variable/system property for configuring the SDK's Resource implementation.

Metrics (alpha)

• The autoconfiguration code for metrics now supports durations to be provided with units attached to them (eg. "100ms"). This includes
  the following environment variables/system properties:
  • OTEL_EXPORTER_OTLP_TIMEOUT/otel.exporter.otlp.timeout
  • OTEL_IMR_EXPORT_INTERVAL/otel.imr.export.interval
