Scans

Scans (schedules) decide when your checks run. Each scan belongs to one connection and defines a recurrence — daily, weekly, or a custom cron expression — plus the set of checks attached to it. Assign tables on an existing scan opens the picker for which checks it should run; Add Scan creates a new one.

A scan can hold checks from more than one table, so grouping related tables' checks into one nightly scan — rather than one schedule per table — keeps the list on this page manageable. See Checks to create the checks a scan attaches to.
