-- Reboots some, or all, of the cache nodes within a provisioned cluster.
-- This operation applies any modified cache parameter groups to the
-- cluster. The reboot operation takes place as soon as possible, and
-- results in a momentary outage to the cluster. During the reboot, the
-- cluster status is set to REBOOTING.
--
-- The reboot causes the contents of the cache (for each cache node being
-- rebooted) to be lost.
--
-- When the reboot is complete, a cluster event is created.
--
-- Rebooting a cluster is currently supported on Memcached and Redis
-- (cluster mode disabled) clusters. Rebooting is not supported on Redis
-- (cluster mode enabled) clusters.
--
-- If you make changes to parameters that require a Redis (cluster mode
-- enabled) cluster reboot for the changes to be applied, see
-- <http://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/nodes.rebooting.html Rebooting a Cluster>
-- for an alternate process.
