Andy Grove created ARROW-6691:
---------------------------------
Summary: [Rust] [DataFusion] Use tokio and Futures instead of
spawning threads
Key: ARROW-6691
URL: https://issues.apache.org/jira/browse/ARROW-6691
Project: Apache Arrow
Issue Type: Sub-task
Components: Rust, Rust - DataFusion
Reporter: Andy Grove
Fix For: 1.0.0
The current implementation of the physical query plan uses "thread::spawn"
which is expensive. We should switch to using Futures and tokio so that we are
launching tasks in a thread pool instead.
