Struct aws_sdk_elasticache::model::ConfigureShard

#[non_exhaustive]
pub struct ConfigureShard { /* private fields */ }

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

Implementations

impl ConfigureShard

pub fn node_group_id(&self) -> Option<&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.

pub fn new_replica_count(&self) -> i32

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)

pub fn preferred_availability_zones(&self) -> Option<&[String]>

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.

pub fn preferred_outpost_arns(&self) -> Option<&[String]>

The outpost ARNs in which the cache cluster is created.

impl ConfigureShard

pub fn builder() -> Builder

Creates a new builder-style object to manufacture ConfigureShard.

Trait Implementations

impl Clone for ConfigureShard

fn clone(&self) -> ConfigureShard

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConfigureShard

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq<ConfigureShard> for ConfigureShard

fn eq(&self, other: &ConfigureShard) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
