Beyond OpenTracing
summary
Demonstrates that a small, agreed event grammar plus structured logging and tracing gives actionable observability: a proof-of-concept grammar-log library (built on logrus) emits verb/object/subject fields, tags those same fields into open tracing + Jaeger, and links to Kafka-based CQRS flow. Under load of 300 requests a single processor shows >30s spans, adding five processors drops tail latency to about 156ms, proving the approach works and reduces cardinality for faster queries.
