| subtext: | | ||
| - Connectors connect pipelines. A connector acts as exporter and a receiver working together. | ||
| For example, a `nopconnector`` may be used to replicate signals by exporting data from one | ||
| pipeline and receiving the data on two other pipelines, which can each process a copy of the data | ||
| in different ways. | ||
| Connectors can also derive one signal from another. For example, a `countconnector` can be used as | ||
| an exporter on a logs pipeline and emit metrics, describing the number of logs, onto a metrics pipeline. |
