Persist Options

 

Clear Persisted State

Manually clear the persisted state of the database. This may be necessary if a large database is persisted and it is affecting the performance of the rest of the system. The state is automatically cleared when options in nodes before the persist node are updated.

The persist state only clears once you have clicked on the clear persisted state button AND you have clicked on the OK button to accept the changes. If you click the cancel button, the state remains unchanged, even if you have selected the clear persisted state button.

 

Persist only if sufficient physical memory available

Check this option if you only want the databases to be persisted to physical memory (RAM) if enough space is available. This option will not use virtual memory (hard disk space) for persist operations. The default status is unchecked.

 

Terminate streams if memory warnings exist

If insufficient memory is available for persist operations (in either physical or virtual memory) a warning message is given and the stream is terminated. To override these messages and continue the stream (without persisting), uncheck this option. The default status is checked.
