----------------------------------
Summary: [Rust] [DataFusion] Allow ParquetExec to parallelize work
based on row groups
Key: ARROW-11056
URL: https://issues.apache.org/jira/browse/ARROW-11056
Project: Apache Arrow
Issue Type: Improvement
Components: Rust - DataFusion
Reporter: Andy Grove
ParquetExec currently parallelizes work by passinging individual files to
threads. It would be nice to be able to do this in a finer-grained way by
assigning row groups and/or column chunks instead. This will be especially
important in distributed systems built on DataFusion.
