---------------------------------
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.
