list_allowed_node_type_modifications#

ElastiCache.Client.list_allowed_node_type_modifications(**kwargs)#

Lists all available node types that you can scale your Redis cluster’s or replication group’s current node type.

When you use the ModifyCacheCluster or ModifyReplicationGroup operations to scale your cluster or replication group, the value of the CacheNodeType parameter must be one of the node types returned by this operation.

Request Syntax

response = client.list_allowed_node_type_modifications(
    CacheClusterId='string',
    ReplicationGroupId='string'
)
Parameters:

  • CacheClusterId (string) –

    The name of the cluster you want to scale up to a larger node instanced type. ElastiCache uses the cluster id to identify the current node type of this cluster and from that to create a list of node types you can scale up to.

    Warning

    You must provide a value for either the CacheClusterId or the ReplicationGroupId.

  • ReplicationGroupId (string) –

    The name of the replication group want to scale up to a larger node type. ElastiCache uses the replication group id to identify the current node type being used by this replication group, and from that to create a list of node types you can scale up to.

    Warning

    You must provide a value for either the CacheClusterId or the ReplicationGroupId.

Return type:

Response Structure

  • (dict) –

    Represents the allowed node types you can use to modify your cluster or replication group.

    • ScaleUpModifications (list) –

      A string list, each element of which specifies a cache node type which you can use to scale your cluster or replication group.

      When scaling up a Redis cluster or replication group using ModifyCacheCluster or ModifyReplicationGroup, use a value from this list for the CacheNodeType parameter.

      • (string) –

    • ScaleDownModifications (list) –

      A string list, each element of which specifies a cache node type which you can use to scale your cluster or replication group. When scaling down a Redis cluster or replication group using ModifyCacheCluster or ModifyReplicationGroup, use a value from this list for the CacheNodeType parameter.

      • (string) –

Exceptions

Examples

Lists all available node types that you can scale your Redis cluster’s or replication group’s current node type up to.

response = client.list_allowed_node_type_modifications(
    CacheClusterId='mycluster',
)

print(response)

Expected Output:

{
    'ScaleUpModifications': [
    ],
    'ResponseMetadata': {
        '...': '...',
    },
