Bases: CfnResource

A CloudFormation AWS::ElastiCache::ReplicationGroup.

The AWS::ElastiCache::ReplicationGroup resource creates an Amazon ElastiCache Redis replication group. A Redis (cluster mode disabled) replication group is a collection of cache clusters, where one of the clusters is a primary read-write cluster and the others are read-only 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 .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

None

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

NodeGroupConfigurationProperty

class CfnReplicationGroup.NodeGroupConfigurationProperty(*, node_group_id=None, primary_availability_zone=None, replica_availability_zones=None, replica_count=None, slots=None)

Bases: object

NodeGroupConfiguration is a property of the AWS::ElastiCache::ReplicationGroup resource that configures an Amazon ElastiCache (ElastiCache) Redis cluster node group.

Parameters
  • node_group_id (Optional[str]) – Either the ElastiCache for Redis supplied 4-digit id or a user supplied id for the node group these configuration values apply to.

  • primary_availability_zone (Optional[str]) – The Availability Zone where the primary node of this node group (shard) is launched.

  • replica_availability_zones (Optional[Sequence[str]]) – A list of Availability Zones to be used for the read replicas. The number of Availability Zones in this list must match the value of ReplicaCount or ReplicasPerNodeGroup if not specified.

  • replica_count (Union[int, float, None]) – The number of read replica nodes in this node group (shard).

  • slots (Optional[str]) – A string of comma-separated values where the first set of values are the slot numbers (zero based), and the second set of values are the keyspaces for each slot. The following example specifies three slots (numbered 0, 1, and 2): 0,1,2,0-4999,5000-9999,10000-16,383 . If you don’t specify a value, ElastiCache allocates keys equally among each slot. When you use an UseOnlineResharding update policy to update the number of node groups without interruption, ElastiCache evenly distributes the keyspaces between the specified number of slots. This cannot be updated later. Therefore, after updating the number of node groups in this way, you should remove the value specified for the Slots property of each NodeGroupConfiguration from the stack template, as it no longer reflects the actual values in each node group. For more information, see UseOnlineResharding Policy .

Return type

Optional[str]

primary_availability_zone

The Availability Zone where the primary node of this node group (shard) is launched.

Return type

Optional[str]

replica_availability_zones

A list of Availability Zones to be used for the read replicas.

The number of Availability Zones in this list must match the value of ReplicaCount or ReplicasPerNodeGroup if not specified.

Return type

Optional[List[str]]

replica_count

The number of read replica nodes in this node group (shard).

Return type

Union[int, float, None]

slots

A string of comma-separated values where the first set of values are the slot numbers (zero based), and the second set of values are the keyspaces for each slot.

The following example specifies three slots (numbered 0, 1, and 2): 0,1,2,0-4999,5000-9999,10000-16,383 .

If you don’t specify a value, ElastiCache allocates keys equally among each slot.

When you use an UseOnlineResharding update policy to update the number of node groups without interruption, ElastiCache evenly distributes the keyspaces between the specified number of slots. This cannot be updated later. Therefore, after updating the number of node groups in this way, you should remove the value specified for the Slots property of each NodeGroupConfiguration from the stack template, as it no longer reflects the actual values in each node group. For more information, see UseOnlineResharding Policy .
