InfoQ: LinkedIn Uses OpenTelemetry to Trace the Member Journey from Tap to Backend
LinkedIn has built an OpenTelemetry-based telemetry platform that links member interactions in its iOS, Android and web apps to the backend services handling them. Requests are correlated using the standard traceId and a pageForestId that groups related requests from one page context. Telemetry is carried over Apache Kafka and stored in ClickHouse, with coordinated head sampling so client and backend activity share a sampling decision.
What changes for platform teams
Platform teams running mixed mobile, web and backend stacks can see a pattern for joining client analytics with distributed traces using OpenTelemetry context propagation and a page-level grouping key. Teams should note the source does not give performance figures, and the 90% debug-volume figure is described as an estimate.
