Andrew Lamb resolved ARROW-11687. --------------------------------- Fix Version/s: 4.0.0 Resolution: Fixed Issue resolved by pull request 9523 [https://github.com/apache/arrow/pull/9523] > [Rust][DataFusion] RepartitionExec Hanging > ------------------------------------------ > > Key: ARROW-11687 > URL: https://issues.apache.org/jira/browse/ARROW-11687 > Project: Apache Arrow > Issue Type: Bug > Components: Rust - DataFusion > Reporter: Mike Seddon > Assignee: Mike Seddon > Priority: Major > Labels: pull-request-available > Fix For: 4.0.0 > > Time Spent: 1h 10m > Remaining Estimate: 0h > > Found an interesting defect where the final partition of the > `RepartitionExec::execute` thread spawner was consistently not being spawned > via `tokio::spawn`. This meant that `RepartitionStream::poll_next` was > sitting waiting forever for data that never arrived. > It looks like a race condition where the `JoinHandle` was not being `await`ed > and something strange going on with the internals of tokio like lazy > evaluation? -- This message was sent by Atlassian Jira (v8.3.4#803005)
