Hi,

Some of our users have Quite Large buckets (up to 20M objects in a
bucket), and AIUI best practice would be to have sharded indexes for
those buckets (of the order of 1 shard per 100k objects).

On a trivial test case (make a 1M-object bucket, shard index to 10
shards, s3cmd ls s3://bucket >/dev/null), sharding makes the bucket
listing slower (not a lot, but a bit).

Are there simple(ish) workflows we could use to demonstrate an
improvement from index sharding?

Thanks,

Matthew

[I understand that Luminous has dynamic resharding, but it seems a bit
unstable for production use; is that still the case?]
