Over time, the Grabbit Job Repository which is stored under /var/grabbit grows and without pruning the data that it is storing, the performance of the Grabbit Status API degrades slowly.
In order to manage that, there is a Clean Repository API available that allows you to delete any Grabbit job history that is older than X hours from the time the API was hit.
The usage is :
POST /grabbit/jobrepository/clean
Parameter: hours=X
where X is the number of hours.This API will delete all the JobInstances, JobExecutions, StepExecutions and ExecutionContexts that were either COMPLETED or FAILED X hours ago from now.
