             Summary: QueryCassandra should not output FlowFiles as soon as the "available rows without fetching" is reached
                 Key: NIFI-12526
                 URL: https://issues.apache.org/jira/browse/NIFI-12526
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Matt Burgess
             Fix For: 1.25.0, 2.0.0


NIFI-5642 introduced the Max Rows Per Flow File and Output Batch Size properties to QueryCassandra, but still uses the internal "rowsAvailableWithoutFetching" variable (whose value comes from the Cassandra ResultSet and defaults to 5000) as a trigger to stop processing rows for a FlowFile. This can cause unexpected behavior, such as getting multiple FlowFiles when only one is expected.

NIFI-5642 also removes the Compression Type property, which might be ok for 2.x but will cause all flows using this property in 1.x to become invalid. On the support (1.x) branch we need to add the property back in, perhaps we can keep it removed for 2.x but we'd want to remove the Cassandra Connect Points property and such to force the user to use a Cassandra Connection controller service. The reason to add the property back is if the Cassandra Contact Points property is used instead of the Cassandra Connection controller service, there is no way to set the Compression Type.
