Andy Grove closed ARROW-4816.
-----------------------------
Resolution: Won't Fix
I am closing this because I feel that it is beyond the scope of
Arrow/DataFusion. DataFusion already supports parallel query execution across
partitioned files and users of DataFusion can choose how they want to partition
their files.
