Adam Taft commented on NIFI-6394:
---------------------------------

There is a hard coded limit that constrains this view to 100 flowfiles max.  
This limit can be seen here:

[https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-framework-bundle/nifi-framework/nifi-web/nifi-web-api/src/main/java/org/apache/nifi/web/dao/impl/StandardConnectionDAO.java#L361]

One starting place as a solution here would be to expose this value as a 
parameter to the REST API, allowing for options in the UI to "show all 
flowfiles in queue". It could potentially also open up avenues for exporting 
the flowfile list as a CSV data file, for dataflow O&M debugging.
