-A compcls:sink.utils.dummy sink component can be useful to run a trace
-processing graph with no sink side effect, for example to perform
-benchmarks. You should prefer this component class for such tasks
-instead of, for example, using a compcls:sink.text.pretty component and
-sending its output to `/dev/null`, as a compcls:sink.text.pretty
-component still performs pretty-printing operations.
