Response Structure

• (dict) --

  • GlobalReplicationGroup (dict) --

    Consists of a primary cluster that accepts writes and an associated secondary cluster that resides in a different AWS 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 AWS region and the role of the replication group.

        • ReplicationGroupId (string) --

          The replication group id of the Global Datastore member.

        • ReplicationGroupRegion (string) --

          The AWS 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. You cannot modify the value of TransitEncryptionEnabled after the cluster is created. To enable in-transit encryption on a cluster you must set TransitEncryptionEnabled to true when you create a cluster.

      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.
