open-telemetry/opentelemetry-java v1.10.0-rc.1

Version 1.10.0 RC1

on GitHub

OpenTelemetry SDK 1.10 will be the first release where the metrics API is considered stable. The Metrics SDK continues to be in development and will be alpha.

We plan to release this RC1 with redundant metrics APIs deprecated, RC2 with them removed, and 1.10.0 the same as RC2 barring unforeseen issues.

API

• The Metrics API has been merged into the opentelemetry-api artifact. OpenTelemetry.getMeterProvider() is the new entrypoint
• BREAKING CHANGE: Bound metrics instruments have been removed for now to allow more time to bake while still providing a stable metrics API
• Double/LongMeasurement.observe has been renamed to record.observe is deprecated in this release
• GlobalMeterProvider has been deprecated. GlobalOpenTelemetry.getMeterProvider should be used instead

SDK

• The semantic conventions have been updated to 1.8.0

Exporter

• The OkHttp gRPC exporters now support experimental retry
• OkHttp dispatcher threads are now spawned as daemon threads
• The JPMS module name for the logs exporter has been fixed
• Metrics exporters can have temporality configured

Metrics (Alpha)

• Some user callbacks have been wrapped to catch exceptions instead of throwing
• MinMaxSumCount/Count aggregation has been removed
• Empty aggregator is renamed to drop
• Cumulative aggregations will not be aggressively dropped every collection cycle

Logs (Alpha)

• LogDataBuilder can now take a SpanContext directly
• SdkLogEmitterProvider.get convenience method added

SDK Extensions

• BREAKING CHANGE: Deprecated trace incubator types (DelegatingSpanData, SpanDataBuidler) have been removed
• BREAKING CHANGE: Deprecated ExecutorServiceSpanProcessor has been removed
