Distributed Tracing Context Propagation

This skill provides expertise in distributed tracing and context propagation across microservices.

Overview

Distributed tracing enables tracking requests as they flow through multiple services, making it possible to understand system behavior and diagnose issues in microservice architectures.

Key Concepts

• W3C Trace Context: Standard for trace context propagation (traceparent, tracestate)
• Span: A single operation within a trace
• Trace ID: Unique identifier for an entire request flow
• Span ID: Unique identifier for a specific operation
• Baggage: Key-value pairs propagated across service boundaries
