--------------------------------
Assignee: Lehel Boér
> Controller level bulletin when content repository backpressure
> --------------------------------------------------------------
>
> Key: NIFI-9434
> URL: https://issues.apache.org/jira/browse/NIFI-9434
> Project: Apache NiFi
> Issue Type: Improvement
> Reporter: Lehel Boér
> Assignee: Lehel Boér
> Priority: Major
> Time Spent: 20m
> Remaining Estimate: 0h
>
> We see more and more users hitting the situation where NiFi seems stuck
> because of the content repo back pressure mechanism that is set by default.
> We should have a controller level bulletin to let the users know what is
> happening.
> This usually happens when all repositories and OS data are using the same
> file system and usage goes over 52%.
> If nifi.content.repository.archive.max.usage.percentage is 50% (default
> value) and nifi.content.repository.archive.backpressure.percentage is not
> set, the effective value of
> nifi.content.repository.archive.backpressure.percentage will be 52%.
> This property is used to control the content repository disk usage percentage
> at which backpressure is applied to the processes writing to the content
> repository. Once this percentage is reached, the content repository will
> refuse any additional writes. Writes will be refused until the archive delete
> process has brought the content repository disk usage percentage below
> nifi.content.repository.archive.max.usage.percentage.
