Distributed Context Propagation: How you can use it to Improve Observability..
summary
Standardizes a single HTTP header for propagating arbitrary key/value request context so services can do traffic prioritization, targeted chaos or fault injection, label synthetics, and attribute infrastructure spend. Demonstrates a live demo built with OpenTelemetry Baggage APIs, explains the W3C spec now at candidate recommendation and how W3C Baggage carries start times and transaction names. Describes a Microsoft-built business transaction protocol that uses baggage to produce end-to-end async metrics and shows how to emit cumulative duration metrics and spans across queues.
