Dec 1, 2025Monthly summary for 2025-12 (signalfx/splunk-otel-ios): Delivered per-session throttling of session replay emissions by introducing SessionReplayEventMemorizer. This ensures splunk.sessionReplay.isRecording is emitted at most once per session, reducing unnecessary events, lowering network usage, and improving runtime performance. Added unit tests validating memorization behavior and atomic emission. No critical bugs were raised; the change enhances telemetry reliability and overall session performance.
