Properties
AutoMinorVersionUpgrade
If you are running Redis engine version 6.0 or later, set this parameter to yes if you want to opt-in to the next minor version upgrade campaign. This parameter is disabled for previous versions.
virtual object AutoMinorVersionUpgrade { get; }
Property Value
System.Object
Remarks
AzMode
Specifies whether the nodes in this Memcached cluster are created in a single Availability Zone or created across multiple Availability Zones in the cluster's region.
virtual string AzMode { get; }
Property Value
System.String
Remarks
This parameter is only supported for Memcached clusters.
If the AZMode

are not specified, ElastiCache assumes single-az
mode.
CacheNodeType
The compute and memory capacity of the nodes in the node group (shard).
string CacheNodeType { get; }
Property Value
System.String
Remarks
The following node types are supported by ElastiCache. Generally speaking, the current generation types provide more memory and computational power at lower cost when compared to their equivalent previous generation counterparts. Changing the CacheNodeType of a Memcached instance is currently not supported. If you need to scale using Memcached, we recommend forcing a replacement update by changing the LogicalResourceId
of the resource.

Additional node type info
CacheParameterGroupName
The name of the parameter group to associate with this cluster.
virtual string CacheParameterGroupName { get; }
Property Value
System.String
Remarks
If this argument is omitted, the default parameter group for the specified engine is used. You cannot use any parameter group which has cluster-enabled='yes'
when creating a cluster.
CacheSecurityGroupNames
A list of security group names to associate with this cluster.
virtual string[] CacheSecurityGroupNames { get; }
Property Value
System.String[]
Remarks
Use this parameter only when you are creating a cluster outside of an Amazon Virtual Private Cloud (Amazon VPC).
CacheSubnetGroupName
The name of the subnet group to be used for the cluster.
virtual string CacheSubnetGroupName { get; }
Property Value
System.String
Remarks
Use this parameter only when you are creating a cluster in an Amazon Virtual Private Cloud (Amazon VPC).
If you're going to launch your cluster in an Amazon VPC, you need to create a subnet group before you start creating a cluster. For more information, see AWS::ElastiCache::SubnetGroup .
ClusterName
A name for the cache cluster.
virtual string ClusterName { get; }
Property Value
System.String
Remarks
If you don't specify a name, AWSCloudFormation generates a unique physical ID and uses that ID for the cache cluster. For more information, see Name Type .
The name must contain 1 to 50 alphanumeric characters or hyphens. The name must start with a letter and cannot end with a hyphen or contain two consecutive hyphens.
Engine
The name of the cache engine to be used for this cluster.
string Engine { get; }
Property Value
System.String
Remarks
Valid values for this parameter are: memcached
| redis
EngineVersion
The version number of the cache engine to be used for this cluster.
virtual string EngineVersion { get; }
Property Value
System.String
Remarks
To view the supported cache engine versions, use the DescribeCacheEngineVersions operation.
Important: You can upgrade to a newer engine version (see Selecting a Cache Engine and Version ), but you cannot downgrade to an earlier engine version. If you want to use an earlier engine version, you must delete the existing cluster or replication group and create it anew with the earlier engine version.
IpDiscovery

| ipv6
.
virtual string IpDiscovery { get; }
Property Value
System.String

virtual string NotificationTopicArn { get; }
Property Value
System.String
Remarks
The Amazon SNS topic owner must be the same as the cluster owner.
NumCacheNodes
The number of cache nodes that the cache cluster should have.
double NumCacheNodes { get; }
Property Value
System.Double
Remarks
However, if the PreferredAvailabilityZone
and PreferredAvailabilityZones
properties were not previously specified and you don't specify any new values, an update requires replacement .
Port
The port number on which each of the cache nodes accepts connections.

System.Nullable<System.Double>
Remarks
PreferredAvailabilityZone
The EC2 Availability Zone in which the cluster is created.
virtual string PreferredAvailabilityZone { get; }

.
Default: System chosen Availability Zone.
PreferredAvailabilityZones
A list of the Availability Zones in which cache nodes are created.
virtual string[] PreferredAvailabilityZones { get; }
Property Value
System.String[]
Remarks
The order of the zones in the list is not important.
This option is only supported on Memcached.
If you are creating your cluster in an Amazon VPC (recommended) you can only locate nodes in Availability Zones that are associated with the subnets in the selected subnet group.
The number of Availability Zones listed must equal the value of NumCacheNodes
.
If you want all the nodes in the same Availability Zone, use PreferredAvailabilityZone
instead, or repeat the Availability Zone multiple times in the list.
Default: System chosen Availability Zones.
PreferredMaintenanceWindow
Specifies the weekly time range during which maintenance on the cluster is performed.
virtual string PreferredMaintenanceWindow { get; }
Property Value
System.String
Remarks
It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period. Valid values for ddd
are:
Specifies the weekly time range during which maintenance on the cluster is performed. It is specified as a range in the format ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC). The minimum maintenance window is a 60 minute period.
Valid values for ddd
are:
Example: sun:23:00-mon:01:30
SnapshotArns
A single-element string list containing an Amazon Resource Name (ARN) that uniquely identifies a Redis RDB snapshot file stored in Amazon S3.
virtual string[] SnapshotArns { get; }
Property Value
System.String[]
Remarks
