Function NewTraceByID

modules/frontend/combiner/trace_by_id.go:42–50

NewTraceByID returns a trace id combiner. The trace by id combiner has a few different behaviors then the others - 404 is a valid response code. if all downstream jobs return 404 then it will return 404 with no body - translate tempopb.TraceByIDResponse to tempopb.Trace. all other combiners pass the

(maxBytes int, contentType api.MarshallingFormat, traceRedactor TraceRedactor)

// - runs the zipkin dedupe logic on the fully combined trace
// - encode the returned trace as either json or proto depending on the request
