Feature Request: Bandwidth Throttling for S3 Transfer Manager

[millems]

The S3 transfer manager should be able to limit (in some way) the bandwidth used when uploading multiple files to prevent saturating the network on a host. This is similar to the feature discussed in this blog post: https://www.instaclustr.com/blog/2016/04/20/cassandra-backups-using-aws-transfermanager/

I am making some changes to Netflix/Priam for backups and was bummed to find that this is not a standard feature yet. It makes sense as S3 is used for backups and while doing a backup you don't want to throttle the bandwidth of the instance.

Using Amazon S3 to do database backups. When transferring the backup to S3, it uses up all available bandwidth. I also use Galera so the combination of the 2 causes actual SQL errors on my other nodes.

We do not currently intend to implement this in V1 of the Java SDK. Keep an eye out on aws/aws-sdk-java-v2#37 for this functionality.
