David Li updated ARROW-12760:
-----------------------------
Component/s: R
> [C++][Python] S3FileSystem: IO thread parallelism limited to 8 threads
> ----------------------------------------------------------------------
>
> Key: ARROW-12760
> URL: https://issues.apache.org/jira/browse/ARROW-12760
> Project: Apache Arrow
> Issue Type: Improvement
> Components: C++, Python, R
> Affects Versions: 4.0.0
> Reporter: Juan Galvez
> Assignee: David Li
> Priority: Major
> Labels: filesystem, performance
> Fix For: 5.0.0
>
>
> On Arrow 4, I'm not able to get more than 8 thread parallelism (for example
> when N threads call fs.ls() with different paths) for S3FileSystem created
> with pyarrow, because the default IO context is created with 8 thread limit
> (hardcoded), and I don't see a way to change this or pass a custom IO context
> through pyarrow APIs. I believe this affects other Arrow filesystem
> implementations as well.
