In the replicator we have a option to reset the checkpoints, by setting reset:true, what is the functionality of it, does it actually restart the whole replication operation, deleting the previously synced data or it resumes from the last successful replication and syncs the missing data.
Set the reset:true option, excepting to restart by deleting all previously synced data and syncing all from the scratch, but was actually syncing from the point where it left.
