Struct aws_sdk_elasticache::client::fluent_builders::DecreaseReplicaCount

pub struct DecreaseReplicaCount { /* private fields */ }

Fluent builder constructing a request to DecreaseReplicaCount.

Dynamically decreases the number of replicas in a Redis (cluster mode disabled) replication group or the number of replica nodes in one or more node groups (shards) of a Redis (cluster mode enabled) replication group. This operation is performed with no cluster down time.

Implementations

impl DecreaseReplicaCount

pub async fn send(
    self
) -> Result<DecreaseReplicaCountOutput, SdkError<DecreaseReplicaCountError>>

Sends the request and returns the response.

If an error occurs, an SdkError will be returned with additional details that can be matched against.

By default, any retryable failures will be retried twice. Retry behavior is configurable with the RetryConfig, which can be set when configuring the client.

pub fn replication_group_id(self, input: impl Into<String>) -> Self

The id of the replication group from which you want to remove replica nodes.

pub fn set_replication_group_id(self, input: Option<String>) -> Self

The id of the replication group from which you want to remove replica nodes.

pub fn new_replica_count(self, input: i32) -> Self

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)

pub fn set_new_replica_count(self, input: Option<i32>) -> Self

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)

pub fn replica_configuration(self, input: ConfigureShard) -> Self

Appends an item to ReplicaConfiguration.

To override the contents of this collection use set_replica_configuration.

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.

pub fn set_replica_configuration(
    self,
    input: Option<Vec<ConfigureShard>>
) -> Self

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.

pub fn replicas_to_remove(self, input: impl Into<String>) -> Self

Appends an item to ReplicasToRemove.

To override the contents of this collection use set_replicas_to_remove.

A list of the node ids to remove from the replication group or node group (shard).

pub fn set_replicas_to_remove(self, input: Option<Vec<String>>) -> Self

A list of the node ids to remove from the replication group or node group (shard).

pub fn apply_immediately(self, input: bool) -> Self

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

pub fn set_apply_immediately(self, input: Option<bool>) -> Self

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