.Support for dynamic bucket resharding
The Ceph Object Gateway now supports the `rgw_dynamic_resharding` parameter. The process for dynamic bucket resharding periodically checks all the Ceph Object Gateway buckets and detects buckets that require resharding. If a bucket has grown larger than specified by the `rgw_max_objs_per_shard` parameter, the Ceph Object Gateway reshards the bucket dynamically in the background. For details, see the link:https://access.redhat.com/documentation/en-us/red_hat_ceph_storage/3/html-single/object_gateway_guide_for_red_hat_enterprise_linux/#resharding-bucket-index-rhcs3[Dynamic Bucket Index Resharding in RHCS 3] section in the Object Gateway Guide for Red Hat Enterprise Linux.
Note that dynamic bucket resharding is disabled in multi-site configuration.
