Description Casey Bodley 2019-10-18 15:01:56 UTC

Description of problem:

Once a bucket index reaches the threshold for dynamic reshard, every PUT Object request in that bucket reschedules the bucket for resharding.

These operations should instead run in a background thread that doesn't affect the write path.
