Andy Grove created ARROW-4739:
---------------------------------
Summary: [Rust] [DataFusion] It should be possible to share a
logical plan between threads
Key: ARROW-4739
URL: https://issues.apache.org/jira/browse/ARROW-4739
Project: Apache Arrow
Issue Type: Improvement
Components: Rust, Rust - DataFusion
Affects Versions: 0.12.0
Reporter: Andy Grove
Fix For: 0.13.0
I want to be able to compile sql to a logical plan and then share that plan
with other threads ( so I can run the same query in parallel on partitions of
my input relation).
A/C
* LogicalPlan uses Arc instead of Rc
* ExecutionContext has a create_logical_plan method
* ExecutionContext.sql() is refactored to call create_logical_plan
