Grafana Tempo: Redaction by query & TraceQL filtering in trace-by-ID v2 (Oct 2026 Community Call)

Trace redaction permanently removes sensitive data from your traces, for when something like an API key ends up in a span attribute. Tempo 3.0 could do it, but only from a list of trace IDs, so you had to go find every affected trace first. In Tempo 3.1 you can hand it a TraceQL query instead.

Separately, trace-by-ID got a filter. You normally ask for a trace and get all of it. Now you can pass a TraceQL query and get back only the spans that match.
