Overview

Note:

When making an API call, you may pass DecreaseReplicaCountMessage data as a 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
}

#apply_immediately ⇒ Boolean

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

Returns:

  • (Boolean)

class DecreaseReplicaCountMessage < Struct.new(
  :replication_group_id,
  :new_replica_count,
  :replica_configuration,
  :replicas_to_remove,
  :apply_immediately)
  SENSITIVE = []
  include Aws::Structure
end

#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)

#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.
