> Thats a good idea, but I guess when we create InputStream in Object Store, the internal of stream will also issuing an HEAD request ( https://github.com/apache/arrow/blob/main/cpp/src/arrow/filesystem/s3fs.cc#L1232 ), I wonder if these are all duplicates... When the source has file size it will be passed here: `https://github.com/apache/arrow/blob/ebc23687cb0376e24a0f002fe710db5ad891c674/cpp/src/arrow/filesystem/s3fs.cc#L2546`, so the function will early exit (https://github.com/apache/arrow/blob/ebc23687cb0376e24a0f002fe710db5ad891c674/cpp/src/arrow/filesystem/s3fs.cc#L1224) But that request you linked is also problematic with regards to threading. I wonder if it would be difficult to refactor it to use `SubmitIO` ? -- This is an automated message from the Apache Git Service.
