Description

In the prioritization explanation of the User Guide, it is stated that OldestFlowFileFirstPrioritizer is the "default scheme that is used if no prioritizers are selected."

(https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#prioritization)

 

 

However, in the actual source code implementation, there is no automatic default setting when prioritizers are not selected.

In such cases, the sorting is done by comparing the ContentClaim of FlowFiles.

(https://github.com/apache/nifi/blob/9a5ec83baa1b3593031f0917659a69e7a36bb0be/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-framework-core/src/main/java/org/apache/nifi/controller/queue/QueuePrioritizer.java#L39-L90) 

 

It looks like the user guide needs to be revised.
