Update the status of the read connector by marking it either Running to mark it active or Paused to pause the connector from running.

Refresh Schedule

The refresh schedule specifies how often Ascend checks the data location to see if there's new data. Ascend will automatically kick off the corresponding big data jobs once new or updated data is discovered.

Processing Priority (optional)

When resources are constrained, Processing Priority will be used to determine which components to schedule first.

Higher priority numbers are scheduled before lower ones. Increasing the priority on a component also causes all its upstream components to be prioritized higher. Negative priorities can be used to postpone work until excess capacity becomes available.
