Struct aws_sdk_rds::client::fluent_builders::ModifyCurrentDBClusterCapacity

pub struct ModifyCurrentDBClusterCapacity<C = DynConnector, M = DefaultMiddleware, R = Standard> { /* fields omitted */ }

Fluent builder constructing a request to ModifyCurrentDBClusterCapacity.

Set the capacity of an Aurora Serverless DB cluster to a specific value.

Aurora Serverless scales seamlessly based on the workload on the DB cluster. In some cases, the capacity might not scale fast enough to meet a sudden change in workload, such as a large number of new transactions. Call ModifyCurrentDBClusterCapacity to set the capacity explicitly.

After this call sets the DB cluster capacity, Aurora Serverless can automatically scale the DB cluster based on the cooldown period for scaling up and the cooldown period for scaling down.

For more information about Aurora Serverless, see Using Amazon Aurora Serverless in the Amazon Aurora User Guide.

If you call ModifyCurrentDBClusterCapacity with the default TimeoutAction, connections that prevent Aurora Serverless from finding a scaling point might be dropped. For more information about scaling points, see Autoscaling for Aurora Serverless in the Amazon Aurora User Guide.

This action only applies to Aurora Serverless DB clusters.

Implementations

impl<C, M, R> ModifyCurrentDBClusterCapacity<C, M, R> where
    C: SmithyConnector,
    M: SmithyMiddleware<C>,
    R: NewRequestPolicy, 

pub async fn send(
    self
) -> Result<ModifyCurrentDbClusterCapacityOutput, SdkError<ModifyCurrentDBClusterCapacityError>> where
    R::Policy: SmithyRetryPolicy<ModifyCurrentDbClusterCapacityInputOperationOutputAlias, ModifyCurrentDbClusterCapacityOutput, ModifyCurrentDBClusterCapacityError, ModifyCurrentDbClusterCapacityInputOperationRetryAlias>, 

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 db_cluster_identifier(self, inp: impl Into<String>) -> Self

The DB cluster identifier for the cluster being modified. This parameter isn't case-sensitive.

Constraints:

• Must match the identifier of an existing DB cluster.

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

The DB cluster identifier for the cluster being modified. This parameter isn't case-sensitive.

Constraints:

• Must match the identifier of an existing DB cluster.

pub fn capacity(self, inp: i32) -> Self

The DB cluster capacity.

When you change the capacity of a paused Aurora Serverless DB cluster, it automatically resumes.

Constraints:

• For Aurora MySQL, valid capacity values are 1, 2, 4, 8, 16, 32, 64, 128, and 256.

• For Aurora PostgreSQL, valid capacity values are 2, 4, 8, 16, 32, 64, 192, and 384.

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

The DB cluster capacity.

When you change the capacity of a paused Aurora Serverless DB cluster, it automatically resumes.

Constraints:

• For Aurora MySQL, valid capacity values are 1, 2, 4, 8, 16, 32, 64, 128, and 256.

• For Aurora PostgreSQL, valid capacity values are 2, 4, 8, 16, 32, 64, 192, and 384.

pub fn seconds_before_timeout(self, inp: i32) -> Self

The amount of time, in seconds, that Aurora Serverless tries to find a scaling point to perform seamless scaling before enforcing the timeout action. The default is 300.

Specify a value between 10 and 600 seconds.

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

The amount of time, in seconds, that Aurora Serverless tries to find a scaling point to perform seamless scaling before enforcing the timeout action. The default is 300.

Specify a value between 10 and 600 seconds.

pub fn timeout_action(self, inp: impl Into<String>) -> Self

The action to take when the timeout is reached, either ForceApplyCapacityChange or RollbackCapacityChange.

ForceApplyCapacityChange, the default, sets the capacity to the specified value as soon as possible.

RollbackCapacityChange ignores the capacity change if a scaling point isn't found in the timeout period.

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

The action to take when the timeout is reached, either ForceApplyCapacityChange or RollbackCapacityChange.

ForceApplyCapacityChange, the default, sets the capacity to the specified value as soon as possible.

RollbackCapacityChange ignores the capacity change if a scaling point isn't found in the timeout period.
