--
-- 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/UserGuide/Clusters.Rebooting.htm Rebooting a Cluster> for an alternate process.
