Struct ConfigureShard

pub struct ConfigureShard {
    pub new_replica_count: i64,
    pub node_group_id: String,
    pub preferred_availability_zones: Option<Vec<String>>,
}

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

Fields

new_replica_count: i64

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)

node_group_id: String

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.

preferred_availability_zones: Option<Vec<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.

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 Default for ConfigureShard

fn default() -> ConfigureShard

Returns the “default value” for a type.

impl PartialEq for ConfigureShard

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

Tests for self and other values to be equal, and is used by ==.

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

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