Github user ijokarumawak commented on the issue: https://github.com/apache/nifi/pull/1877 @markap14 Thanks for the suggestion, I agree with that. I've made following changes: - Added default method at RecordReaderFactory, so that existing processors needn't change - Reverted changes to classes those can utilize the newly added default method, PutElasticsearchHttpRecord, AbstractPutHDFSRecord, PutParquetTes, PutDatabaseRecord, FlowFileEnumerator and FlowFileTable. This reduced the volume of this PR, a little bit. - Rebased with the latest master, and updated few new classes to meet the new RecordSetWriterFactory method signatures. Local contrib check passed without issue. Also tested a live flow with various record readers and writers. https://gist.github.com/ijokarumawak/a6c33eef30d0cd9786eab7eeacccb7ff I hope it's now ready to be merged, thanks!
