  SENSITIVE = []
  include Aws::Structure
end

#new_replica_count ⇒ Integer

The number of read replica nodes you want at the completion of this operation. For Valkey or Redis OSS (cluster mode disabled) replication groups, this is the number of replica nodes in the replication group. For Valkey or Redis OSS (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:

  • Valkey or Redis OSS (cluster mode disabled)

    • If Multi-AZ is enabled: 1

    • If Multi-AZ is not enabled: 0

  • Valkey or Redis OSS (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 Valkey or Redis OSS (cluster mode enabled) replication group. The `ConfigureShard` has three members: `NewReplicaCount`, `NodeGroupId`, and `PreferredAvailabilityZones`.

Returns:
