Developers can now gain deeper insights into their Pub/Sub client's publish behavior. The new PubsubClientTelemetry schema, intended to be sent via the x-goog-pubsub-client-telemetry header, includes a publishOperation field. This PublishOperation object exposes hedgedAttemptCount to track publish hedging attempts and publishStartTime to indicate when a publish call was initiated. This offers better end-to-end latency visibility and enhanced debugging capabilities for client-side issues.
