        The set of arguments for constructing a ReplicationGroup resource.
        :param pulumi.Input[str] replication_group_description: A user-created description for the replication group.
        :param pulumi.Input[bool] apply_immediately: Specifies whether any modifications are applied immediately, or during the next maintenance window. Default is `false`.
        :param pulumi.Input[bool] at_rest_encryption_enabled: Whether to enable encryption at rest.
        :param pulumi.Input[str] auth_token: The password used to access a password protected server. Can be specified only if `transit_encryption_enabled = true`.
        :param pulumi.Input[bool] auto_minor_version_upgrade: Specifies whether a minor engine upgrades will be applied automatically to the underlying Cache Cluster instances during the maintenance window. This parameter is currently not supported by the AWS API. Defaults to `true`.
        :param pulumi.Input[bool] automatic_failover_enabled: Specifies whether a read-only replica will be automatically promoted to read/write primary if the existing primary fails. If enabled, `number_cache_clusters` must be greater than 1. Must be enabled for Redis (cluster mode enabled) replication groups. Defaults to `false`.
        :param pulumi.Input[Sequence[pulumi.Input[str]]] availability_zones: A list of EC2 availability zones in which the replication group's cache clusters will be created. The order of the availability zones in the list is not important.
        :param pulumi.Input['ReplicationGroupClusterModeArgs'] cluster_mode: Create a native Redis cluster. `automatic_failover_enabled` must be set to true. Cluster Mode documented below. Only 1 `cluster_mode` block is allowed. One of `number_cache_clusters` or `cluster_mode` is required. Note that configuring this block does not enable cluster mode, i.e. data sharding, this requires using a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[str] engine: The name of the cache engine to be used for the clusters in this replication group. The only valid value is `redis`.
        :param pulumi.Input[str] engine_version: The version number of the cache engine to be used for the cache clusters in this replication group. If the version is 6 or higher, only the major version can be set, e.g. `6.x`, otherwise, specify the full version desired, e.g. `5.0.6`. The actual engine version used is returned in the attribute `engine_version_actual`, defined below.
        :param pulumi.Input[str] final_snapshot_identifier: The name of your final node group (shard) snapshot. ElastiCache creates the snapshot from the primary node in the cluster. If omitted, no final snapshot will be made.
        :param pulumi.Input[str] global_replication_group_id: The ID of the global replication group to which this replication group should belong. If this parameter is specified, the replication group is added to the specified global replication group as a secondary replication group; otherwise, the replication group is not part of any global replication group.
        :param pulumi.Input[str] kms_key_id: The ARN of the key that you wish to use if encrypting at rest. If not supplied, uses service managed encryption. Can be specified only if `at_rest_encryption_enabled = true`.
        :param pulumi.Input[str] maintenance_window: Specifies the weekly time range for when maintenance on the cache cluster is performed. The format is `ddd:hh24:mi-ddd:hh24:mi` (24H Clock UTC). The minimum maintenance window is a 60 minute period. Example: `sun:05:00-sun:09:00`
        :param pulumi.Input[bool] multi_az_enabled: Specifies whether to enable Multi-AZ Support for the replication group. If `true`, `automatic_failover_enabled` must also be enabled. Defaults to `false`.
        :param pulumi.Input[str] node_type: The instance class to be used. See AWS documentation for information on [supported node types](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/CacheNodes.SupportedTypes.html) and [guidance on selecting node types](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/nodes-select-size.html). Required unless `global_replication_group_id` is set. Cannot be set if `global_replication_group_id` is set.
        :param pulumi.Input[str] notification_topic_arn: An Amazon Resource Name (ARN) of an SNS topic to send ElastiCache notifications to. Example: `arn:aws:sns:us-east-1:012345678999:my_sns_topic`
        :param pulumi.Input[int] number_cache_clusters: The number of cache clusters (primary and replicas) this replication group will have. If Multi-AZ is enabled, the value of this parameter must be at least 2. Updates will occur before other modifications. One of `number_cache_clusters` or `cluster_mode` is required.
        :param pulumi.Input[str] parameter_group_name: The name of the parameter group to associate with this replication group. If this argument is omitted, the default cache parameter group for the specified engine is used. To enable "cluster mode", i.e. data sharding, use a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[int] port: The port number on which each of the cache nodes will accept connections. For Memcache the default is 11211, and for Redis the default port is 6379.
        :param pulumi.Input[str] replication_group_id: The replication group identifier. This parameter is stored as a lowercase string.
        :param pulumi.Input[Sequence[pulumi.Input[str]]] security_group_ids: One or more Amazon VPC security groups associated with this replication group. Use this parameter only when you are creating a replication group in an Amazon Virtual Private Cloud
        :param pulumi.Input[Sequence[pulumi.Input[str]]] security_group_names: A list of cache security group names to associate with this replication group.
        :param pulumi.Input[Sequence[pulumi.Input[str]]] snapshot_arns: A list of Amazon Resource Names (ARNs) that identify Redis RDB snapshot files stored in Amazon S3. The names object names cannot contain any commas.
        :param pulumi.Input[str] snapshot_name: The name of a snapshot from which to restore data into the new node group. Changing the `snapshot_name` forces a new resource.
        :param pulumi.Input[int] snapshot_retention_limit: The number of days for which ElastiCache will retain automatic cache cluster snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, then a snapshot that was taken today will be retained for 5 days before being deleted. If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off. Please note that setting a `snapshot_retention_limit` is not supported on cache.t1.micro cache nodes
        :param pulumi.Input[str] snapshot_window: The daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster. The minimum snapshot window is a 60 minute period. Example: `05:00-09:00`
        :param pulumi.Input[str] subnet_group_name: The name of the cache subnet group to be used for the replication group.
        :param pulumi.Input[bool] transit_encryption_enabled: Whether to enable encryption in transit.

        :param pulumi.Input[bool] auto_minor_version_upgrade: Specifies whether a minor engine upgrades will be applied automatically to the underlying Cache Cluster instances during the maintenance window. This parameter is currently not supported by the AWS API. Defaults to `true`.
        :param pulumi.Input[bool] automatic_failover_enabled: Specifies whether a read-only replica will be automatically promoted to read/write primary if the existing primary fails. If enabled, `number_cache_clusters` must be greater than 1. Must be enabled for Redis (cluster mode enabled) replication groups. Defaults to `false`.
        :param pulumi.Input[Sequence[pulumi.Input[str]]] availability_zones: A list of EC2 availability zones in which the replication group's cache clusters will be created. The order of the availability zones in the list is not important.
        :param pulumi.Input[bool] cluster_enabled: Indicates if cluster mode is enabled.
        :param pulumi.Input['ReplicationGroupClusterModeArgs'] cluster_mode: Create a native Redis cluster. `automatic_failover_enabled` must be set to true. Cluster Mode documented below. Only 1 `cluster_mode` block is allowed. One of `number_cache_clusters` or `cluster_mode` is required. Note that configuring this block does not enable cluster mode, i.e. data sharding, this requires using a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[str] configuration_endpoint_address: The address of the replication group configuration endpoint when cluster mode is enabled.
        :param pulumi.Input[str] engine: The name of the cache engine to be used for the clusters in this replication group. The only valid value is `redis`.
        :param pulumi.Input[str] engine_version: The version number of the cache engine to be used for the cache clusters in this replication group. If the version is 6 or higher, only the major version can be set, e.g. `6.x`, otherwise, specify the full version desired, e.g. `5.0.6`. The actual engine version used is returned in the attribute `engine_version_actual`, defined below.
        :param pulumi.Input[str] engine_version_actual: The running version of the cache engine.
        :param pulumi.Input[str] final_snapshot_identifier: The name of your final node group (shard) snapshot. ElastiCache creates the snapshot from the primary node in the cluster. If omitted, no final snapshot will be made.
        :param pulumi.Input[str] global_replication_group_id: The ID of the global replication group to which this replication group should belong. If this parameter is specified, the replication group is added to the specified global replication group as a secondary replication group; otherwise, the replication group is not part of any global replication group.
        :param pulumi.Input[str] kms_key_id: The ARN of the key that you wish to use if encrypting at rest. If not supplied, uses service managed encryption. Can be specified only if `at_rest_encryption_enabled = true`.

        :param pulumi.Input[int] number_cache_clusters: The number of cache clusters (primary and replicas) this replication group will have. If Multi-AZ is enabled, the value of this parameter must be at least 2. Updates will occur before other modifications. One of `number_cache_clusters` or `cluster_mode` is required.
        :param pulumi.Input[str] parameter_group_name: The name of the parameter group to associate with this replication group. If this argument is omitted, the default cache parameter group for the specified engine is used. To enable "cluster mode", i.e. data sharding, use a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[int] port: The port number on which each of the cache nodes will accept connections. For Memcache the default is 11211, and for Redis the default port is 6379.

        Provides an ElastiCache Replication Group resource.

        For working with a [Memcached cluster](https://docs.aws.amazon.com/AmazonElastiCache/latest/mem-ug/WhatIs.html) or a
        [single-node Redis instance (Cluster Mode Disabled)](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/WhatIs.html),
        see the `elasticache.Cluster` resource.

        > **Note:** When you change an attribute, such as `engine_version`, by
        default the ElastiCache API applies it in the next maintenance window. Because
        of this, this provider may report a difference in its planning phase because the
        actual modification has not yet taken place. You can use the
        `apply_immediately` flag to instruct the service to apply the change
        immediately. Using `apply_immediately` can result in a brief downtime as
        servers reboots.
        See the AWS Documentation on
        [Modifying an ElastiCache Cache Cluster](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Clusters.Modify.html)
        for more information.

        > **Note:** Any attribute changes that re-create the resource will be applied immediately, regardless of the value of `apply_immediately`.

        > **Note:** Be aware of the terminology collision around "cluster" for `elasticache.ReplicationGroup`. For example, it is possible to create a ["Cluster Mode Disabled [Redis] Cluster"](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Clusters.Create.CON.Redis.html). With "Cluster Mode Enabled", the data will be stored in shards (called "node groups"). See [Redis Cluster Configuration](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/cluster-create-determine-requirements.html#redis-cluster-configuration) for a diagram of the differences. To enable cluster mode, use a parameter group that has cluster mode enabled. The default parameter groups provided by AWS end with ".cluster.on", for example `default.redis6.x.cluster.on`.

        ## Example Usage
        ### Redis Cluster Mode Disabled

        To create a single shard primary with single read replica:

        ```python
        import pulumi
        import pulumi_aws as aws

        example = aws.elasticache.ReplicationGroup("example",
            automatic_failover_enabled=True,
            availability_zones=[
                "us-west-2a",
                "us-west-2b",
            ],
            node_type="cache.m4.large",
            number_cache_clusters=2,
            parameter_group_name="default.redis3.2",
            port=6379,
            replication_group_description="test description")
        ```

        You have two options for adjusting the number of replicas:

        * Adjusting `number_cache_clusters` directly. This will attempt to automatically add or remove replicas, but provides no granular control (e.g. preferred availability zone, cache cluster ID) for the added or removed replicas. This also currently expects cache cluster IDs in the form of `replication_group_id-00#`.
        * Otherwise for fine grained control of the underlying cache clusters, they can be added or removed with the `elasticache.Cluster` resource and its `replication_group_id` attribute. In this situation, you will need to utilize [`ignoreChanges`](https://www.pulumi.com/docs/intro/concepts/programming-model/#ignorechanges) to prevent perpetual differences with the `number_cache_cluster` attribute.

        ```python
        import pulumi
        import pulumi_aws as aws

        example = aws.elasticache.ReplicationGroup("example",
            automatic_failover_enabled=True,
            availability_zones=[
                "us-west-2a",
                "us-west-2b",
            ],
            replication_group_description="test description",
            node_type="cache.m4.large",
            number_cache_clusters=2,
            parameter_group_name="default.redis3.2",
            port=6379)
        replica = None
        if 1 == True:
            replica = aws.elasticache.Cluster("replica", replication_group_id=example.id)
        ```
        ### Redis Cluster Mode Enabled

        To create two shards with a primary and a single read replica each:

        ```python
        import pulumi
        import pulumi_aws as aws

        baz = aws.elasticache.ReplicationGroup("baz",
            automatic_failover_enabled=True,
            cluster_mode=aws.elasticache.ReplicationGroupClusterModeArgs(
                num_node_groups=2,
                replicas_per_node_group=1,
            ),
            node_type="cache.t2.small",
            parameter_group_name="default.redis3.2.cluster.on",
            port=6379,
            replication_group_description="test description")
        ```

        > **Note:** We currently do not support passing a `primary_cluster_id` in order to create the Replication Group.

        > **Note:** Automatic Failover is unavailable for Redis versions earlier than 2.8.6,
        and unavailable on T1 node types. For T2 node types, it is only available on Redis version 3.2.4 or later with cluster mode enabled. See the [High Availability Using Replication Groups](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/Replication.html) guide
        for full details on using Replication Groups.
        ### Creating a secondary replication group for a global replication group

        A Global Replication Group can have one one two secondary Replication Groups in different regions. These are added to an existing Global Replication Group.

        ```python
        import pulumi
        import pulumi_aws as aws

        primary = aws.elasticache.ReplicationGroup("primary",
            replication_group_description="primary replication group",
            engine="redis",
            engine_version="5.0.6",
            node_type="cache.m5.large",
            number_cache_clusters=1,
            opts=pulumi.ResourceOptions(provider=aws["other_region"]))
        example = aws.elasticache.GlobalReplicationGroup("example",
            global_replication_group_id_suffix="example",
            primary_replication_group_id=primary.id,
            opts=pulumi.ResourceOptions(provider=aws["other_region"]))
        secondary = aws.elasticache.ReplicationGroup("secondary",
            replication_group_description="secondary replication group",
            global_replication_group_id=example.global_replication_group_id,
            number_cache_clusters=1)
        ```

        ## Import

        ElastiCache Replication Groups can be imported using the `replication_group_id`, e.g.

        ```sh
         $ pulumi import aws:elasticache/replicationGroup:ReplicationGroup my_replication_group replication-group-1
        ```

        :param str resource_name: The name of the resource.
        :param pulumi.ResourceOptions opts: Options for the resource.
        :param pulumi.Input[bool] apply_immediately: Specifies whether any modifications are applied immediately, or during the next maintenance window. Default is `false`.
        :param pulumi.Input[bool] at_rest_encryption_enabled: Whether to enable encryption at rest.

        :param pulumi.Input[bool] auto_minor_version_upgrade: Specifies whether a minor engine upgrades will be applied automatically to the underlying Cache Cluster instances during the maintenance window. This parameter is currently not supported by the AWS API. Defaults to `true`.
        :param pulumi.Input[bool] automatic_failover_enabled: Specifies whether a read-only replica will be automatically promoted to read/write primary if the existing primary fails. If enabled, `number_cache_clusters` must be greater than 1. Must be enabled for Redis (cluster mode enabled) replication groups. Defaults to `false`.
        :param pulumi.Input[Sequence[pulumi.Input[str]]] availability_zones: A list of EC2 availability zones in which the replication group's cache clusters will be created. The order of the availability zones in the list is not important.
        :param pulumi.Input[pulumi.InputType['ReplicationGroupClusterModeArgs']] cluster_mode: Create a native Redis cluster. `automatic_failover_enabled` must be set to true. Cluster Mode documented below. Only 1 `cluster_mode` block is allowed. One of `number_cache_clusters` or `cluster_mode` is required. Note that configuring this block does not enable cluster mode, i.e. data sharding, this requires using a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[str] engine: The name of the cache engine to be used for the clusters in this replication group. The only valid value is `redis`.
        :param pulumi.Input[str] engine_version: The version number of the cache engine to be used for the cache clusters in this replication group. If the version is 6 or higher, only the major version can be set, e.g. `6.x`, otherwise, specify the full version desired, e.g. `5.0.6`. The actual engine version used is returned in the attribute `engine_version_actual`, defined below.
        :param pulumi.Input[str] final_snapshot_identifier: The name of your final node group (shard) snapshot. ElastiCache creates the snapshot from the primary node in the cluster. If omitted, no final snapshot will be made.
        :param pulumi.Input[str] global_replication_group_id: The ID of the global replication group to which this replication group should belong. If this parameter is specified, the replication group is added to the specified global replication group as a secondary replication group; otherwise, the replication group is not part of any global replication group.
        :param pulumi.Input[str] kms_key_id: The ARN of the key that you wish to use if encrypting at rest. If not supplied, uses service managed encryption. Can be specified only if `at_rest_encryption_enabled = true`.
        :param pulumi.Input[str] maintenance_window: Specifies the weekly time range for when maintenance on the cache cluster is performed. The format is `ddd:hh24:mi-ddd:hh24:mi` (24H Clock UTC). The minimum maintenance window is a 60 minute period. Example: `sun:05:00-sun:09:00`
        :param pulumi.Input[bool] multi_az_enabled: Specifies whether to enable Multi-AZ Support for the replication group. If `true`, `automatic_failover_enabled` must also be enabled. Defaults to `false`.
        :param pulumi.Input[str] node_type: The instance class to be used. See AWS documentation for information on [supported node types](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/CacheNodes.SupportedTypes.html) and [guidance on selecting node types](https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/nodes-select-size.html). Required unless `global_replication_group_id` is set. Cannot be set if `global_replication_group_id` is set.
        :param pulumi.Input[str] notification_topic_arn: An Amazon Resource Name (ARN) of an SNS topic to send ElastiCache notifications to. Example: `arn:aws:sns:us-east-1:012345678999:my_sns_topic`
        :param pulumi.Input[int] number_cache_clusters: The number of cache clusters (primary and replicas) this replication group will have. If Multi-AZ is enabled, the value of this parameter must be at least 2. Updates will occur before other modifications. One of `number_cache_clusters` or `cluster_mode` is required.
        :param pulumi.Input[str] parameter_group_name: The name of the parameter group to associate with this replication group. If this argument is omitted, the default cache parameter group for the specified engine is used. To enable "cluster mode", i.e. data sharding, use a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[int] port: The port number on which each of the cache nodes will accept connections. For Memcache the default is 11211, and for Redis the default port is 6379.
        :param pulumi.Input[str] replication_group_description: A user-created description for the replication group.
        :param pulumi.Input[str] replication_group_id: The replication group identifier. This parameter is stored as a lowercase string.

        :param pulumi.Input[Sequence[pulumi.Input[str]]] security_group_names: A list of cache security group names to associate with this replication group.
        :param pulumi.Input[Sequence[pulumi.Input[str]]] snapshot_arns: A list of Amazon Resource Names (ARNs) that identify Redis RDB snapshot files stored in Amazon S3. The names object names cannot contain any commas.
        :param pulumi.Input[str] snapshot_name: The name of a snapshot from which to restore data into the new node group. Changing the `snapshot_name` forces a new resource.
        :param pulumi.Input[int] snapshot_retention_limit: The number of days for which ElastiCache will retain automatic cache cluster snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, then a snapshot that was taken today will be retained for 5 days before being deleted. If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off. Please note that setting a `snapshot_retention_limit` is not supported on cache.t1.micro cache nodes
        :param pulumi.Input[str] snapshot_window: The daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster. The minimum snapshot window is a 60 minute period. Example: `05:00-09:00`
        :param pulumi.Input[str] subnet_group_name: The name of the cache subnet group to be used for the replication group.
        :param pulumi.Input[bool] transit_encryption_enabled: Whether to enable encryption in transit.

        :param pulumi.Input[str] configuration_endpoint_address: The address of the replication group configuration endpoint when cluster mode is enabled.
        :param pulumi.Input[str] engine: The name of the cache engine to be used for the clusters in this replication group. The only valid value is `redis`.
        :param pulumi.Input[str] engine_version: The version number of the cache engine to be used for the cache clusters in this replication group. If the version is 6 or higher, only the major version can be set, e.g. `6.x`, otherwise, specify the full version desired, e.g. `5.0.6`. The actual engine version used is returned in the attribute `engine_version_actual`, defined below.

        :param pulumi.Input[int] number_cache_clusters: The number of cache clusters (primary and replicas) this replication group will have. If Multi-AZ is enabled, the value of this parameter must be at least 2. Updates will occur before other modifications. One of `number_cache_clusters` or `cluster_mode` is required.
        :param pulumi.Input[str] parameter_group_name: The name of the parameter group to associate with this replication group. If this argument is omitted, the default cache parameter group for the specified engine is used. To enable "cluster mode", i.e. data sharding, use a parameter group that has the parameter `cluster-enabled` set to true.
        :param pulumi.Input[int] port: The port number on which each of the cache nodes will accept connections. For Memcache the default is 11211, and for Redis the default port is 6379.

        :param pulumi.Input[Sequence[pulumi.Input[str]]] snapshot_arns: A list of Amazon Resource Names (ARNs) that identify Redis RDB snapshot files stored in Amazon S3. The names object names cannot contain any commas.
        :param pulumi.Input[str] snapshot_name: The name of a snapshot from which to restore data into the new node group. Changing the `snapshot_name` forces a new resource.
        :param pulumi.Input[int] snapshot_retention_limit: The number of days for which ElastiCache will retain automatic cache cluster snapshots before deleting them. For example, if you set SnapshotRetentionLimit to 5, then a snapshot that was taken today will be retained for 5 days before being deleted. If the value of SnapshotRetentionLimit is set to zero (0), backups are turned off. Please note that setting a `snapshot_retention_limit` is not supported on cache.t1.micro cache nodes
        :param pulumi.Input[str] snapshot_window: The daily time range (in UTC) during which ElastiCache will begin taking a daily snapshot of your cache cluster. The minimum snapshot window is a 60 minute period. Example: `05:00-09:00`
