Ben Icore commented on NIFI-949:
--------------------------------
This is still very much an issue even with 0.7.1 if the system has been
running under any kind of load for even a few hours, there is a significant
amount of repo cleanup that happens when the system is restarted.
> Allow configuration of cleanup resources

> Key: NIFI-949
> URL: https://issues.apache.org/jira/browse/NIFI-949
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Brandon DeVries
> Priority: Minor
>
> Allow the allocation of resource to the cleanup of the content and provenance
> repositories to be configurable. There are times at which the resources
> spent performing cleanup activities can degrade the operation of the flow
> sufficiently to cause problems. Sometimes this requires removing the
> offending node from the cluster to allow it to clean up without taking on new
> data (and thus backing up). Making the cleanup resources configurable could
> prevent such a situation by allowing them to be reduced under times of heavy
> load to keep the node useable.
