Response Structure

(dict) –
- GlobalReplicationGroup (dict) –
  
  Consists of a primary cluster that accepts writes and an associated secondary cluster that resides in a different Amazon region. The secondary cluster accepts only reads. The primary cluster automatically replicates updates to the secondary cluster.
  - The GlobalReplicationGroupIdSuffix represents the name of the Global datastore, which is what you use to associate a secondary cluster.
  - GlobalReplicationGroupId (string) –
    
    The name of the Global datastore
  - GlobalReplicationGroupDescription (string) –
    
    The optional description of the Global datastore
  - Status (string) –
    
    The status of the Global datastore
  - CacheNodeType (string) –
    
    The cache node type of the Global datastore
  - Engine (string) –
    
    The Elasticache engine. For Redis only.
  - EngineVersion (string) –
    
    The Elasticache Redis engine version.
  - Members (list) –
    
    The replication groups that comprise the Global datastore.
    - (dict) –
      
      A member of a Global datastore. It contains the Replication Group Id, the Amazon region and the role of the replication group.
      - ReplicationGroupId (string) –
        
        The replication group id of the Global datastore member.
      - ReplicationGroupRegion (string) –
        
        The Amazon region of the Global datastore member.
      - Role (string) –
        
        Indicates the role of the replication group, primary or secondary.
      - AutomaticFailover (string) –
        
        Indicates whether automatic failover is enabled for the replication group.
      - Status (string) –
        
        The status of the membership of the replication group.
  - ClusterEnabled (boolean) –
    
    A flag that indicates whether the Global datastore is cluster enabled.
  - GlobalNodeGroups (list) –
    
    Indicates the slot configuration and global identifier for each slice group.
    - (dict) –
      
      Indicates the slot configuration and global identifier for a slice group.
      - GlobalNodeGroupId (string) –
        
        The name of the global node group
      - Slots (string) –
        
        The keyspace for this node group
  - AuthTokenEnabled (boolean) –
    
    A flag that enables using an AuthToken (password) when issuing Redis commands.
    
    Default: false
  - TransitEncryptionEnabled (boolean) –
    
    A flag that enables in-transit encryption when set to true.
    
    Required: Only available when creating a replication group in an Amazon VPC using redis version 3.2.6, 4.x or later.
  - AtRestEncryptionEnabled (boolean) –
    
    A flag that enables encryption at rest when set to true.
    
    You cannot modify the value of AtRestEncryptionEnabled after the replication group is created. To enable encryption at rest on a replication group you must set AtRestEncryptionEnabled to true when you create the replication group.
    
    Required: Only available when creating a replication group in an Amazon VPC using redis version 3.2.6, 4.x or later.
  - ARN (string) –
    
    The ARN (Amazon Resource Name) of the global replication group.
