Andy Grove created ARROW-8784:
---------------------------------
Summary: [Rust] [DataFusion] Remove use of Arc from LogicalPlan
Key: ARROW-8784
URL: https://issues.apache.org/jira/browse/ARROW-8784
Project: Apache Arrow
Issue Type: Improvement
Components: Rust, Rust - DataFusion
Reporter: Andy Grove
Fix For: 1.0.0
The reason that the LogicalPlan currently uses Arc rather than Box is to
support the ability to pass the logical plan between threads.
I am no longer sure that this is a requirement, and if it is, then it would
perhaps be better to serialize the plan to JSON using the serde crate.
