lidavidm opened a new pull request #11189: URL: https://github.com/apache/arrow/pull/11189
This creates a new concatenating generator which converts AsyncGenerator<optional<vector<T>>> to AsyncGenerator<T> and supports async-reentrancy. When combined with a readahead generator, this enables us to get parallelism in scanning Parquet files. This also properly chunks each row group into smaller batches as mentioned in ARROW-14024, though we can add more specific tests in that JIRA (and fix the issue for IPC as well). -- This is an automated message from the Apache Git Service.
