[GitHub] [arrow-datafusion] andygrove commented on issue #2730: LocalFileSystem Not sorted by file name， As a result, the data lines queried in multiple files are out of order.

andygrove commented on issue #2730:
URL: https://github.com/apache/arrow-datafusion/issues/2730#issuecomment-1156582037

   Partitions are processed in parallel on multiple threads so DataFusion cannot provide any guarantee of ordering of results unless the query contains an ORDER BY clause.
