> QueryCassandra processor : output FlowFiles as soon fetch_size is reached
> -------------------------------------------------------------------------
>
> Key: NIFI-5642
> URL: https://issues.apache.org/jira/browse/NIFI-5642
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.7.1
> Reporter: André Gomes Lamas Otero
> 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.
