.Ceph Object Gateway's default bucket-index shards increased to 11 The default number of bucket-index shards for new buckets has been increased, from 1 to 11. This increases the amount of write throughput for small buckets and delays the onset of dynamic resharding. This change only affects new deployments and zones. For existing deployments, you can change this default value using the `radosgw-admin zonegroup modify --bucket-index-max-shards=11` command. If the zonegroup is part of a realm, the change must be committed with `radosgw-admin period update --commit` command. If a commit is not done, then the change will take effect until after the Ceph Object Gateways are restarted. NOTE: After an upgrade, the new default value has to be increased manually, but on new {storage-product} 4.1 deployments the new default value is set automatically.
