NAME

Paws::ElastiCache::ConfigureShard

USAGE

This class represents one of two things:

Arguments in a call to a service

Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.

As an example, if Att1 is expected to be a Paws::ElastiCache::ConfigureShard object:

  $service_obj->Method(Att1 => { NewReplicaCount => $value, ..., PreferredOutpostArns => $value  });

Results returned from an API call

Use accessors for each attribute. If Att1 is expected to be an Paws::ElastiCache::ConfigureShard object:

  $result = $service_obj->Method(...);
  $result->Att1->NewReplicaCount

DESCRIPTION

Node group (shard) configuration options when adding or removing replicas. Each node group (shard) configuration has the following members: NodeGroupId, NewReplicaCount, and PreferredAvailabilityZones.

ATTRIBUTES

REQUIRED NewReplicaCount => Int

The number of replicas you want in this node group at the end of this operation. The maximum value for "NewReplicaCount" is 5. The minimum value depends upon the type of Redis replication group you are working with.

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

•: Redis (cluster mode disabled)

If Multi-AZ: 1
If Multi-AZ: 0

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

REQUIRED NodeGroupId => Str

The 4-digit id for the node group you are configuring. For Redis (cluster mode disabled) replication groups, the node group id is always 0001. To find a Redis (cluster mode enabled)'s node group's (shard's) id, see Finding a Shard's Id (https://docs.aws.amazon.com/AmazonElastiCache/latest/red-ug/shard-find-id.html).

PreferredAvailabilityZones => ArrayRef[Str|Undef]

A list of "PreferredAvailabilityZone" strings that specify which availability zones the replication group's nodes are to be in. The nummber of "PreferredAvailabilityZone" values must equal the value of "NewReplicaCount" plus 1 to account for the primary node. If this member of "ReplicaConfiguration" is omitted, ElastiCache for Redis selects the availability zone for each of the replicas.

PreferredOutpostArns => ArrayRef[Str|Undef]

The outpost ARNs in which the cache cluster is created.
