Prepare: I collect as much information for the users before onboarding so I can prepare for their use case in the future and set things up. Preshard: After created the bucket: radosgw-admin bucket reshard --bucket=ex-bucket --num-shards=101 Also when you shard the buckets, you need to use prime numbers.
