> Key: NIFI-9029
> URL: https://issues.apache.org/jira/browse/NIFI-9029
> Project: Apache NiFi
> Issue Type: Task
> Components: Documentation & Website
> Affects Versions: 1.13.2
> Reporter: Ryan Hendrickson
> Assignee: Alasdair Brown
> Priority: Critical
> Fix For: 1.15.0
>
>
> Our team recently upgraded to 1.13.2 from 1.11.4. The performance
> improvements caused a number of servers which see quite a bit of data to
> perform better. However, we began experiencing "frozen NiFi's". NiFi's that
> appear fine, but will not process any data. We determined the file I/O
> improvements from the 1.11.4 to 1.13.2 release were significant enough for
> us, that we increased the amount of data passing through them to go from the
> 50% archive to exceeding the 52% archive backpressure percentage prior to the
> archive job completing.
> This locked-up all our NiFi's causing us to revert.
> How did we figure this out?
> We came across a mailing list email outlining the _*undocumented*_ NiFi
> Property *nifi.content.repository.archive.backpressure.percentage* causing
> the issue.
> This is a repeatable issue. Something more should be done to warn the user
> on the UI that this has happened. Until then. Here is a ticket outlining
> all of the missing properties in the [Sys Admin
> Guide|https://nifi.apache.org/docs/nifi-docs/html/administration-guide.html]
> as compared to the real properties defined in
> [NiFiProperties.java|https://github.com/apache/nifi/blob/main/nifi-commons/nifi-properties/src/main/java/org/apache/nifi/util/NiFiProperties.java].
