Telemetry Talks ep 4: Retroactive sampling and OpenTelemetry
This episode of Telemetry Talks explores the evolution of an OTLP/gRPC tracing pipeline for VictoriaTraces within OpenTelemetry and VictoriaMetrics, including a shift from standard gRPC-Go to a simplified HTTP/2-based implementation to reduce complexity and improve flexibility.
Together with the our guest, Jiekun, we revisited the VictoriaMetrics KubeCon talk ideas on tail-based and retroactive sampling — and their impact on the broader OpenTelemetry community.
