The Delete Queues option lets you purge data that is waiting to be replicated to the target database.
Stop the Change Selector before using the Delete Queues option.
This option is useful for instances where you are using Model Update because you want to reinitialize with the latest changes. Any new data left waiting in the queue may not be up-to-date and may corrupt the new version of the model.
Another instance in which you use the option to delete queues is if you want to reset your source and target tables completely. For this, you are starting fresh and do not want to apply any leftover data.
If you attempt to delete the queue for a request when its table's Change Selector is running, you receive an error.
