**Is your feature request related to a problem or challenge? Please describe what you are trying to do.** From what I have read predicate pushdown filtering in parquet works on row-group level, so in my case I should be able to optimize reads by manually closing row-group. **Describe the solution you'd like** Simply expose in ArrowWriter API flush_row_group method that flushes all buffered rows. **Describe alternatives you've considered** I have considered using SerializedFileWriter, however due to my lack of complete understanding of definition, repetition levels I would prefer to use high level API like ArrowWriter. -- This is an automated message from the Apache Git Service.
