TEMPO 3.1 RELEASE: KAFKA, TRACE REDACTION, AND TRACEQL METRICS

Summary from the TLDR Data newsletter

Grafana Tempo 3.1 makes Kafka-backed tracing easier to run with TLS, additional authentication methods, rack-aware reads, and configurable producer compression. Query-based redaction can permanently remove sensitive trace data without enumerating trace IDs, while sampling-aware TraceQL metrics improve analysis of incomplete telemetry. Operators should use redaction dry-runs and complete the upgrade before applying time-bounded deletions.
