Juan Galvez created ARROW-12760: ----------------------------------- Summary: [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 Affects Versions: 4.0.0 Reporter: Juan Galvez
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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
