context-manager-opentelemetry

OpenTelemetry context propagation library

Context Manager that delegates ThreadLocal management to the default OpenTelemetry Context storage.

Obtaining the current context value is delegated to io.opentelemetry.context.Context.current(). Initializing a new context value is delegated to io.opentelemetry.context.Context.makeCurrent().

Adding the context-manager-opentelemetry jar to the classpath is all that is needed to include the OpenTelemetry Context in ContextSnapshots. This propagates the context to other threads using the ContextAwareExecutorService or ContextAwareCompletableFuture.

Also, any function ..WithContext in the core.function package automatically activates the context snapshot around the function body.
