    [ https://issues.apache.org/jira/browse/NIFI-5989?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16763123#comment-16763123 ] 

Joseph Witt commented on NIFI-5989:
-----------------------------------

[~mattyb149] [~markap14] [~goosalex] this one appears to have a patch and relates to Kudu for which much work in this release has happened.  Do we have a reviewer that can evaluate this now?  If not i'll move it off the fix version.

> Current "Batch size" property of PutKudu affects both: the number of Flowfiles pulled per OnTrigger and the size of the Kudu client modification buffer.
> If the Flowfiles contain a considerable amount of records, then a disproportionate amount of data is pulled in and deserialized into memory, when in AUTO_FLUSH_BACKGROUND mode. 
> We propose introducing a separate setting for the batch size of FlowFiles.
