Data quality: Default schedule for data metric functions (Pending)¶
Attention
This behavior change is in the 2025_07 bundle.
For the current status of the bundle, refer to Bundle History.
Data metric functions (DMFs) are associated with tables and views to run data quality checks on a regular schedule. This change introduces the concept of a default schedule, and behaves as follows:
- Before the change:
- You must modify a table or view to set a schedule before you can associate a DMF with the object. There is no default schedule. - If you run an ALTER <object> UNSET DATA_METRIC_SCHEDULE command, the DMF schedule is set to an empty string, which suspends all DMF evaluations on the table or view. 
- After the change:
- Every table and view has a default schedule of one hour. All you need to do to run data quality checks at one-hour intervals is associate a DMF with an object. You can change the default at any time. - If you run an ALTER <object> UNSET DATA_METRIC_SCHEDULE command, the DMF schedule is reset to the default of one hour. - If you want to suspend all DMFs associated with an object, set the schedule to an empty string.
