[jira] [Created] (ARROW-12255) [Rust] [Ballista] Integrate
scheduler with DataFusion
Andy Grove created ARROW-12255:
----------------------------------
Summary: [Rust] [Ballista] Integrate scheduler with DataFusion
Key: ARROW-12255
URL: https://issues.apache.org/jira/browse/ARROW-12255
Project: Apache Arrow
Issue Type: New Feature
Components: Rust - Ballista, Rust - DataFusion
Reporter: Andy Grove
Assignee: Andy Grove
Fix For: 5.0.0
The Ballista scheduler breaks a query down into stages based on changes in partitioning int he plan, where each stage is broken down into tasks that can be executed concurrently.
Rather than trying to run all the partitions at once, Ballista executors process n concurrent tasks at a time and then request new tasks from the scheduler.
This approach would help DataFusion scale better and it would be ideal to use the same scheduler to scale across cores in DataFusion and across nodes in Ballista.
