paginate(**kwargs)#

Creates an iterator that will paginate through responses from DAX.Client.describe_clusters().

    - Status (string) –
      
      The current status of the cluster.
    - ClusterDiscoveryEndpoint (dict) –
      
      The endpoint for this DAX cluster, consisting of a DNS name, a port number, and a URL. Applications should use the URL to configure the DAX client to find their cluster.
      - Address (string) –
        
        The DNS hostname of the endpoint.
      - Port (integer) –

      - URL (string) –
        
        The URL that applications should use to connect to the endpoint. The default ports are 8111 for the “dax” protocol and 9111 for the “daxs” protocol.
    - NodeIdsToRemove (list) –
      
      A list of nodes to be removed from the cluster.
      - (string) –

        A system-generated identifier for the node.
        
        Endpoint (dict) –
        
        The endpoint for the node, consisting of a DNS name and a port number. Client applications can connect directly to a node endpoint, if desired (as an alternative to allowing DAX client software to intelligently route requests and responses to nodes in the DAX cluster.
        
        Address (string) –
        
        The DNS hostname of the endpoint.
