There are dbmlsync event hooks that you can implement to control when synchronization occurs.

With the sp_hook_dbmlsync_end hook, you can use the Restart row in the #hook_dict table to decide at the end of each synchronization if dbmlsync should repeat the synchronization.

With the sp_hook_dbmlsync_delay hook you can create a delay at the beginning of each synchronization that allows you to choose the time to proceed with synchronization. With this hook it is possible to delay for a fixed amount of time or to poll periodically, waiting for some condition to be satisfied.

This method is not available when the Dbmlsync API or the SQL SYNCHRONIZE statement is used.
