%%
%% Amazon ElastiCache is a web service that makes it easier to set up,
%% operate, and scale a distributed cache in the cloud.
%%
%% With ElastiCache, customers get all of the benefits of a high-performance,
%% in-memory cache with less of the administrative burden involved in
%% launching and managing a distributed cache. The service makes setup,
%% scaling, and cluster failure handling much simpler than in a self-managed
%% cache deployment.
%%
%% In addition, through integration with Amazon CloudWatch, customers get
%% enhanced visibility into the key performance statistics associated with
%% their cache and can receive alarms if a part of their cache runs hot.

%% @doc Creates a Redis (cluster mode disabled) or a Redis (cluster mode
%% enabled) replication group.
%%
%% This API can be used to create a standalone regional replication group or
%% a secondary replication group associated with a Global datastore.
%%
%% A Redis (cluster mode disabled) replication group is a collection of
%% clusters, where one of the clusters is a read/write primary and the others
%% are read-only replicas. Writes to the primary are asynchronously
%% propagated to the replicas.
%%
%% A Redis cluster-mode enabled cluster is comprised of from 1 to 90 shards
%% (API/CLI: node groups). Each shard has a primary node and up to 5
%% read-only replica nodes. The configuration can range from 90 shards and 0
%% replicas to 15 shards and 5 replicas, which is the maximum number or
%% replicas allowed.
%%
%% The node or shard limit can be increased to a maximum of 500 per cluster
%% if the Redis engine version is 5.0.6 or higher. For example, you can
%% choose to configure a 500 node cluster that ranges between 83 shards (one
%% primary and 5 replicas per shard) and 500 shards (single primary and no
%% replicas). Make sure there are enough available IP addresses to
%% accommodate the increase. Common pitfalls include the subnets in the
%% subnet group have too small a CIDR range or the subnets are shared and
%% heavily used by other clusters. For more information, see Creating a
%% Subnet Group. For versions below 5.0.6, the limit is 250 per cluster.
%%
%% To request a limit increase, see Amazon Service Limits and choose the
%% limit type Nodes per cluster per instance type.
%%
%% When a Redis (cluster mode disabled) replication group has been
%% successfully created, you can add one or more read replicas to it, up to a
%% total of 5 read replicas. If you need to increase or decrease the number
%% of node groups (console: shards), you can avail yourself of ElastiCache
%% for Redis' scaling. For more information, see Scaling ElastiCache for
%% Redis Clusters in the ElastiCache User Guide.
