-- | The /DeleteCacheCluster/ operation deletes a previously provisioned cache
-- cluster. /DeleteCacheCluster/ deletes all associated cache nodes, node
-- endpoints and the cache cluster itself. When you receive a successful
-- response from this operation, Amazon ElastiCache immediately begins deleting
-- the cache cluster; you cannot cancel or revert this operation.
--
-- This API cannot be used to delete a cache cluster that is the last read
-- replica of a replication group that has automatic failover mode enabled.
