// 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
// (https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/SubnetGroups.Creating.html).
// For versions below 5.0.6, the limit is 250 per cluster. To request a limit
// increase, see Amazon Service Limits
// (https://docs.aws.amazon.com/general/latest/gr/aws_service_limits.html) 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
// (https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Scaling.html) in
