route to different sinks with different response times

[evanzhang87]

sources:
  sourceA:
    type: logstash

transforms:
  dispatcher:
    type: route
    inputs:
      - sourceA
    reroute_unmatched: false
    route:
      r1: .type == "sys"
      r2: .type != "sys"

sinks:
  sinkA: // faster response
    type: kafka
    inputs:
      - dispatcher.r1
  sinkB:  // slower response
    type: kafka
    inputs:
      - dispatcher.r2

Will this have a buckets effect? Will sourceA's response time depend on sinkB?

Hey! Yes, it will. See https://vector.dev/docs/about/concepts/#backpressure for a description of the way back-pressure works when fanning out like you are here.
