Group by Trace processor

Supported pipeline types: traces Status: in development

This processor collects all the spans from the same trace, waiting a pre-determined amount of time before releasing the trace to the next processor. The expectation is that, generally, traces will be complete after the given time.

This processor should be used whenever a processor requires grouped traces to make decisions, such as a tail-based sampler or a per-trace metrics processor.

The batch processor shouldn't be used before this processor, as this one will probably undo part (or much) of the work that the batch processor performs. It's fine to have the batch processor to run right after this one, and every entry in the batch will be a complete trace.

Please refer to config.go for the config spec.

Examples:

processors:
  groupbytrace:
  groupbytrace/2:
    wait_duration: 10s
    num_traces: 1000

Refer to config.yaml for detailed examples on using the processor.
