[jira] [Created] (ARROW-8774) [Rust] [DataFusion] Improve threading model

Andy Grove created ARROW-8774:
---------------------------------

             Summary: [Rust] [DataFusion] Improve threading model
                 Key: ARROW-8774
                 URL: https://issues.apache.org/jira/browse/ARROW-8774
             Project: Apache Arrow
          Issue Type: Improvement
          Components: Rust, Rust - DataFusion
            Reporter: Andy Grove
            Assignee: Andy Grove
             Fix For: 1.0.0


DataFusion currently spawns one thread per partition and this results in poor performance if there are more partitions than available cores/threads. It would be better to have a thread-pool that defaults to number of available cores.
