To build an upload, dbmlsync must scan the transaction log. Usually it does this at the beginning of synchronization. However,
when synchronizations are scheduled or when the sp_hook_dbmlsync_delay hook is used, dbmlsync by default scans the log in
the pause that occurs before synchronization. This behavior is more efficient because when synchronization begins the log
is already at least partially scanned. This default behavior is called logscan polling.
Logscan polling is on by default but only has an effect when synchronizations are scheduled using the Schedule extended option
or when sp_hook_dbmlsync_delay hook is used. When in effect, polling occurs at set intervals. The default interval is 1 minute,
but it can be changed with the dbmlsync -pp option.
This option is identical to the extended option DisablePolling=on.
