Raw Spans Grouper

Streaming Job that converts a group of raw spans into traces.

Description

Hypertrace Ingestion Pipeline

hypertrace-oc-collector collects spans from tracers like Jaeger, Zipkin and writes them to kafka which will be then converted to raw-spans by span-normalizer Job. raw-spans-grouper fetches this raw-spans from kafka and creates structured traces out of it based on the trace id and the parent span id in the spans.
