Datagroup Actions

You can perform the following actions on datagroups from the Datagroups Admin page:

  1. Click on the LookML button to open the LookML model file where the datagroup is defined.
  2. Select Reset Cache from the gear menu to immediately invalidate the cached results for all Explores using that datagroup.
  3. Select Trigger Datagroup from the gear menu to invalidate the cached results for all Explores and rebuild all PDTs using that datagroup. The PDT rebuild will begin based on the next time specified in the connection’s PDT And Datagroup Maintenance Schedule field, such as every five minutes. Any scheduled data deliveries that use the datagroup as a trigger will be sent when the triggered datagroup reaches the ready state.
