             Summary: Add a "Bin Termination Check" to MergeContent
                 Key: NIFI-14166
                 URL: https://issues.apache.org/jira/browse/NIFI-14166
             Project: Apache NiFi
          Issue Type: Improvement
          Components: Extensions
            Reporter: Mark Payne
            Assignee: Mark Payne


MergeContent allows specifying the min and max size of a Bin, which is 
typically what we want in order to create reasonably sized bins. However, there 
are times when we have data that necessitates that we stop binning data 
together and create a new bin, because even though the correlation attribute is 
the same, the incoming FlowFile cannot be added to the existing bin. This is 
especially the case when FIFO prioritizers are used and the ordering of the 
data matters.

To accommodate this, we can add a new "Bin Termination Check" property. If a 
FlowFile causes the check to return a value of {{{}true{}}}, we should merge 
the bin and start a new one.
