@pvillard31 Did you try the new `CalculateParquetRowGroupOffsets` processor too? In this one, you cannot configre the number of records in splits, because it splits by row group boundaries. But since it calculates where the `ParquetReader` should seek in the file, the data is distributed and processed much more efficiently. My measurements showed major improvement in performance. You can also combine the two as `CalculateParquetRowGroupOffsets -> CalculateParquetOffsets`, so you would still have the control of how many records fall into a single FlowFile too. I can't really do any further improvement to this, due to API limitations of the underlying library. -- This is an automated message from the Apache Git Service.
