[jira] [Commented] (NIFI-7583) Update User Guide to explain how
swapping affects queue prioritization
[ https://issues.apache.org/jira/browse/NIFI-7583?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17153857#comment-17153857 ]
Ryan Hendrickson commented on NIFI-7583:
----------------------------------------
For the documentation, I'd ask that you consider adding something to the "Configure Connection -> Available Prioritizer" Help Icon.. Right now it says "Available prioritizers that could reprioritize FlowFiles in this work queue." And the Selected Prioritizers says: "Prioritizers that have been selected to prioritize FlowFiles in this work queue." Something to notify users of the behavior and NiFi attribute that controls it would be helpful.
For a long term improvement.. What about providing an override?.. Similar to the box for "Size Threshold" and "Back Pressure Object Threshold", could there be one with "Priority Queue Size", set to default to 20,000, but could be modified on a connection-by-connection basis? That'd help mitigate what I'm afraid is going to happen when we jacked the size from 20,000 to 200,000 for the entire server instead of the single queue.
