General Suggestions for Tuning the Scheduler

The following TaskDefinition options determine how the Scheduler handles tasks after they are completed:

• resultLimit — Controls how many seconds task results are kept after the task has completed. The default setting varies for different tasks. A setting of zero immediately removes tasks after completion.

• resultOption — Controls what action is taken when repeated instances of a task are started. The default setting is delete, which removes previous task instances.

These default settings are designed to optimize memory by shortening the lifetime of finished Scheduler tasks. Unless there is a compelling reason to change these settings, use the defaults.

If you want to immediately delete tasks that completed successfully, but you also want to keep tasks containing errors long enough to debug, you can do the following:

• Set the resultLimit to a small value, such as 3600 seconds.

• Set the saveOnlyOnError value to true.

With these two settings, Waveset will only store the task results if the task has an error or warning Result Item. This configuration can improve the performance of some tasks by allowing them to bypass being stored in the repository when they complete.
