26 | A compcls:sink.utils.dummy sink component can be useful to run a trace |
| 27 | processing graph with no sink side effect, for example to perform | |
| 28 | benchmarks. Prefer a compcls:sink.utils.dummy component class for such | |
| 29 | tasks to, for example, a compcls:sink.text.pretty component and sending | |
| 30 | its output to `/dev/null`, as a compcls:sink.text.pretty component still | |
| 31 | performs formatting operations. | |
