 ### Sync Settings
 After pointing Mixpanel at your group table, you can select a Sync Type option. The options are: 
-- Time Based: If you select this, you will need to add a mapping to an Insert Time column. We expect this to be a monotonically increasing TIMESTAMP_NTZ. We use this as a water mark to figure out which group profile updates are new and ingest them. This allows you to only send Mixpanel delta updates, which would mean paying lower egress and compute costs.

 - Full Sync: With this option, Mixpanel will periodically do a full sync on the entire table. This means that periodically, we will update all users' value even if there are no delta updates. 
 
 Check the preview to ensure that everything looks correct, and then create the sync.
