## Which issue does this PR close? Closes #7079 ## Rationale for this change When writing out multiple partitions to multiple parquet files, we can speed up the operation by writing all parquet files in parallel on multiple cpu cores. Parallelizing the serialization of a single parquet file is more complex and will need upstream changes in arrow-rs. There is already an issue open for this here https://github.com/apache/arrow-rs/issues/1718. ## What changes are included in this PR? Spawn a tokio task for each parquet file being written. ## Are these changes tested? Yes by existing tests. ## Are there any user-facing changes? No other than better write performance when writing multiple parquet files on a system with multiple cpu cores. -- This is an automated message from the Apache Git Service.
