.Servicing reads of immutable objects with the new `ceph-immutable-object-cache` daemon
With this release, the new `ceph-immutable-object-cache` daemon can be deployed on a hypervisor node to service the reads of immutable objects, for example a parent image snapshot. The new `parent_cache` librbd plugin coordinates with the daemon on every read from the parent image, adding the result to the cache wherever necessary. This reduces latency in scenarios where multiple virtual machines are concurrently sharing a golden image.
For more information, see the link:{block-dev-guide}#management-of-ceph-immutable-object-cache-daemons[_Management of `ceph-immutable-object-cache`daemons_] chapter in the _{storage-product} Block device guide_.
