Before this PR, we were launching one thread per Parquet file in ParquetExec. This works well when the number of files is small but does not scale well when there are hundreds of files. This PR respects the context's `max_concurrency` configuration option and uses it to split the files up into lists per partition/thread. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
