I think something else that might be related is the fact that (currently) DataFusion execution tries to start all partitions concurrently. This means that depending on how fast IO comes in and the details of the Tokio scheduler, sometimes it will have far too many open files at once (it might end up opening 100 input parquet files, for example, even if there are only 8 cores available for processing) -- This is an automated message from the Apache Git Service.
