### Is your feature request related to a problem or challenge? When writing to a parquet file in parallel, the implementation in https://github.com/apache/arrow-datafusion/pull/7562, will potentially buffer parquet data faster than can be written to the final output as there is no back pressure and the intermediate files are all buffered in memory. As described by @devinjdangelo in https://github.com/apache/arrow-datafusion/pull/7562#discussion_r1327960903 > I think the best possible solution would consume the sub parquet files incrementally from memory as they are produced, rather than buffering the entire file. ### Describe the solution you'd like I would like to see the output row groups written as they are produced, rather than all buffered and written after the fact, as suggested by @dev ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
