Overview

Note:

When passing DecreaseReplicaCountMessage as input to an Aws::Client method, you can use a vanilla Hash:

{
  replication_group_id: "String", # required
  new_replica_count: 1,
  replica_configuration: [
    {
      node_group_id: "AllowedNodeGroupId", # required
      new_replica_count: 1, # required
      preferred_availability_zones: ["String"],
      preferred_outpost_arns: ["String"],
    },
  ],
  replicas_to_remove: ["String"],
  apply_immediately: false, # required
}

Instance Attribute Details

#apply_immediately ⇒ Boolean

If True, the number of replica nodes is decreased immediately. ApplyImmediately=False is not currently supported.

Returns:

  • (Boolean) —

    If True, the number of replica nodes is decreased immediately.

#new_replica_count ⇒ Integer

The number of read replica nodes you want at the completion of this operation. For Redis (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Redis (cluster mode enabled) replication groups, this is the number of replica nodes in each of the replication group\'s node groups.

The minimum number of replicas in a shard or replication group is:

  • Redis (cluster mode disabled)

    • If Multi-AZ is enabled: 1

    • If Multi-AZ is not enabled: 0

  • Redis (cluster mode enabled): 0 (though you will not be able to failover to a replica if your primary node fails)

Returns:

  • (Integer) —

    The number of read replica nodes you want at the completion of this operation.

#replica_configuration ⇒ Array<Types::ConfigureShard>

A list of ConfigureShard objects that can be used to configure each shard in a Redis (cluster mode enabled) replication group. The ConfigureShard has three members: NewReplicaCount, NodeGroupId, and PreferredAvailabilityZones.

Returns:

  • (Array<Types::ConfigureShard>) —

    A list of ConfigureShard objects that can be used to configure each shard in a Redis (cluster mode enabled) replication group.

#replicas_to_remove ⇒ Array<String>

A list of the node ids to remove from the replication group or node group (shard).

Returns:

  • (Array<String>) —

    A list of the node ids to remove from the replication group or node group (shard).

#replication_group_id ⇒ String

The id of the replication group from which you want to remove replica nodes.

Returns:

  • (String) —

    The id of the replication group from which you want to remove replica nodes.
