> Hmm, noticed that the execution freezes when I set io_thread_count <= fragment_readahead (testing with Pyarrow). A deadlock probably? I wonder if it's introduced by this change, or if it's a bug that just manifests now because of higher concurrency. I think I have observed such a freeze recently with a recent Pyarrow release, but couldn't reproduce. @eeroel https://github.com/apache/arrow/pull/37918/files#r1340188707 I think this is the problem that we call blocking in async execution. It's a bit like this problem I fixed: https://github.com/apache/arrow/pull/37514 -- This is an automated message from the Apache Git Service.
