create_global_replication_group

ElastiCache.Client.create_global_replication_group(**kwargs)

Global Datastore for Redis offers fully managed, fast, reliable and secure cross-region replication. Using Global Datastore for Redis, you can create cross-region read replica clusters for ElastiCache for Redis to enable low-latency reads and disaster recovery across regions. For more information, see Replication Across Regions Using Global Datastore.

• The GlobalReplicationGroupIdSuffix is the name of the Global datastore.

• The PrimaryReplicationGroupId represents the name of the primary cluster that accepts writes and will replicate updates to the secondary cluster.

Request Syntax

response = client.create_global_replication_group(
    GlobalReplicationGroupIdSuffix='string',
    GlobalReplicationGroupDescription='string',
    PrimaryReplicationGroupId='string'
)

Parameters:

• GlobalReplicationGroupIdSuffix (string) –

  [REQUIRED]

  The suffix name of a Global datastore. Amazon ElastiCache automatically applies a prefix to the Global datastore ID when it is created. Each Amazon Region has its own prefix. For instance, a Global datastore ID created in the US-West-1 region will begin with “dsdfu” along with the suffix name you provide. The suffix, combined with the auto-generated prefix, guarantees uniqueness of the Global datastore name across multiple regions.

  For a full list of Amazon Regions and their respective Global datastore iD prefixes, see Using the Amazon CLI with Global datastores.

• GlobalReplicationGroupDescription (string) – Provides details of the Global datastore

• PrimaryReplicationGroupId (string) –

  [REQUIRED]

  The name of the primary cluster that accepts writes and will replicate updates to the secondary cluster.

Return type:

dict

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.
