Summary: Document Missing Properties in the Sys Admin Guide
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
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].
