-------------------------------------
Summary: Queues are not prioritized properly when files are
swapped out
Key: NIFI-8440
URL: https://issues.apache.org/jira/browse/NIFI-8440
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Affects Versions: 1.13.2, 1.9.2
Reporter: Andrew Glowacki
When a queue has files swapped out and a new file is added to it, it doesn't
check whether or not that new file's priority is high enough for it to be in
the non-swapped (active) set. This isn't normally a problem, however if the
active files are waiting for the new file before they can be transferred, this
might result in a stoppage (such as when you have a processor similar to
MergeContent with the defragmentation strategy). This is also an problem if you
expect a large queue of files to be prioritized properly but are not actively
being consumed or added to in large enough volume.
