Andy Grove created ARROW-9707: --------------------------------- Summary: [Rust] [DataFusion] Re-implement threading model Key: ARROW-9707 URL: https://issues.apache.org/jira/browse/ARROW-9707 Project: Apache Arrow Issue Type: Sub-task Components: Rust, Rust - DataFusion Reporter: Andy Grove Assignee: Andy Grove Fix For: 2.0.0
The current threading model is very simple and does not scale. We currently use 1-2 dedicated threads per partition and they all run simultaneously, which is a huge problem if you have more partitions than logical or physical cores. This task is to re-implement the threading model so that query execution uses a fixed (configurable) number of threads. Work will be broken down into stages and tasks and each in-process executor (running on a dedicated thread) will process its queue of tasks. This process will be driven by a scheduler. -- This message was sent by Atlassian Jira (v8.3.4#803005)
