GlobalReplicationGroup

class GlobalReplicationGroup : KotlinCustomResource

Provides an ElastiCache Global Replication Group resource, which manages replication between two or more Replication Groups in different regions. For more information, see the ElastiCache User Guide.

Example Usage

Global replication group with one secondary replication group

The global replication group depends on the primary group existing. Secondary replication groups depend on the global replication group. the provider dependency management will handle this transparently using resource value references.

Managing Redis Engine Versions

The initial Redis version is determined by the version set on the primary replication group. However, once it is part of a Global Replication Group, the Global Replication Group manages the version of all member replication groups. The member replication groups must have lifecycle.ignore_changes[engine_version] set, or the provider will always return a diff. In this example, the primary replication group will be created with Redis 6.0, and then upgraded to Redis 6.2 once added to the Global Replication Group. The secondary replication group will be created with Redis 6.2.

Properties

Link copied to clipboard
val arn: Output<String>

The ARN of the ElastiCache Global Replication Group.

Link copied to clipboard
val atRestEncryptionEnabled: Output<Boolean>

A flag that indicate whether the encryption at rest is enabled.

Link copied to clipboard
val authTokenEnabled: Output<Boolean>

A flag that indicate whether AuthToken (password) is enabled.

Link copied to clipboard
val automaticFailoverEnabled: Output<Boolean>

Specifies whether read-only replicas will be automatically promoted to read/write primary if the existing primary fails. When creating, by default the Global Replication Group inherits the automatic failover setting of the primary replication group.

Link copied to clipboard
val cacheNodeType: Output<String>

The instance class used. See AWS documentation for information on supported node types and guidance on selecting node types. When creating, by default the Global Replication Group inherits the node type of the primary replication group.

Link copied to clipboard
val clusterEnabled: Output<Boolean>

Indicates whether the Global Datastore is cluster enabled.

Link copied to clipboard
val engine: Output<String>

The name of the cache engine to be used for the clusters in this global replication group.

Link copied to clipboard
val engineVersion: Output<String>

Redis version to use for the Global Replication Group. When creating, by default the Global Replication Group inherits the version of the primary replication group. If a version is specified, the Global Replication Group and all member replication groups will be upgraded to this version. Cannot be downgraded without replacing the Global Replication Group and all member replication groups. When the version is 7 or higher, the major and minor version should be set, e.g., 7.2. When the version is 6, the major and minor version can be set, e.g., 6.2, or the minor version can be unspecified which will use the latest version at creation time, e.g., 6.x. The actual engine version used is returned in the attribute engine_version_actual, see Attribute Reference below.

Link copied to clipboard
val engineVersionActual: Output<String>

The full version number of the cache engine running on the members of this global replication group.

Link copied to clipboard
val globalNodeGroups: Output<List<GlobalReplicationGroupGlobalNodeGroup>>

Set of node groups (shards) on the global replication group. Has the values:

Link copied to clipboard
val globalReplicationGroupDescription: Output<String>?

A user-created description for the global replication group.

Link copied to clipboard
val globalReplicationGroupId: Output<String>

The full ID of the global replication group.

Link copied to clipboard
val globalReplicationGroupIdSuffix: Output<String>

The suffix name of a Global Datastore. If global_replication_group_id_suffix is changed, creates a new resource.

Link copied to clipboard
val numNodeGroups: Output<Int>

The number of node groups (shards) on the global replication group.

Link copied to clipboard
val parameterGroupName: Output<String>?

An ElastiCache Parameter Group to use for the Global Replication Group. Required when upgrading a major engine version, but will be ignored if left configured after the upgrade is complete. Specifying without a major version upgrade will fail. Note that ElastiCache creates a copy of this parameter group for each member replication group.

Link copied to clipboard
val primaryReplicationGroupId: Output<String>

The ID of the primary cluster that accepts writes and will replicate updates to the secondary cluster. If primary_replication_group_id is changed, creates a new resource.
