> 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.
