    Thanks for the comments @mattyb149!
    Your understanding is correct regarding the intent of this change, I'll 
take a look on QueryDatabaseTable to understand how to add an "Output Batch 
Size" parameter on QueryCassandra processor.

>            Priority: Major
>
> When I'm using QueryCassandra alongside with fetch_size parameter I expected 
> that as soon my reader reaches the fetch_size the processor outputs some data 
> to be processed by the next processor, but QueryCassandra reads all the data, 
> then output the flow files.
> I'll start to work on a patch for this situation, I'll appreciate any 
> suggestion.
