Configure polling
To turn a source channel into an automatic feed, you set how often DASH checks it and how far back its first poll should reach. You do this in the Automation Setup step of the material creation wizard, or later by editing the material record.
Set the poll interval
Section titled “Set the poll interval”The poll interval is how often DASH checks the source for new documents.
- Open the material and go to its source channel — either in the Automation Setup step of the creation wizard, or by editing the material record.
- Enter the poll interval. The shortest allowed interval is 60 seconds; DASH runs due channels about once a minute.
- Leave the interval empty to disable scheduled polling — the channel keeps its configuration but will not poll on its own until you set an interval again.
Choose the ingestion start point
Section titled “Choose the ingestion start point”The start point governs how far back the very first poll reaches. After the first poll, DASH only picks up documents newer than the last successful poll — so the start point matters just once, at the beginning. Choose one of:
- From today — ingest only documents that appear from now on. Existing files at the source are ignored.
- From a specific date — ingest documents dated on or after a date you pick, plus everything new afterwards.
- All existing documents — ingest everything already at the source, then keep going with new documents.
Activate or pause the channel
Section titled “Activate or pause the channel”- Activate the channel to start scheduled polling. A channel must be active and have a definition map pinned before it will poll.
- Pause the channel at any time to stop polling. Its configuration is kept, and you can resume later — resuming picks up from where it left off.
DASH records the last poll status and the last error message on the channel so you can see at a glance whether polling is healthy. If a channel hits repeated authentication failures it is disabled automatically; a configuration error (such as a missing required field) disables it immediately. Both cases are cleared when you fix the problem and resume. See Automated ingestion troubleshooting.
