> I mean that maybe some flags in https://docs.aws.amazon.com/cli/latest/userguide/cli-configure-envvars.html helps, but I didn't test them. S3FS in arrow fs just wraps the S3 SDK, maybe we can find some existing solutions in S3 and port from them? Right, I couldn't find any AWS flag that would help here. There is also this issue about switching to the S3CrtClient in AWS SDK: https://github.com/apache/arrow/issues/18923 I actually tried the CRT client with Arrow, it's a drop-in replacement, and in my limited test cases it does give higher throughput than the old S3Client. Not sure what the main sources of performance boost are, but it does handle the IP address discovery in some clever way and automatically splits GET requests into smaller ranges and parallelizes. The main problem I've noticed is that it actually does a HEAD request for each byte-range GET, in order to validate the range, so this would be an issue for low-latency use cases (I've been hoping that HEAD requests could be eliminated 😅). -- This is an automated message from the Apache Git Service.
