Struct FailoverDBClusterFluentBuilder 

Source 
pub struct FailoverDBClusterFluentBuilder { /* private fields */ }
Expand description

Fluent builder constructing a request to FailoverDBCluster.

Forces a failover for a DB cluster.

For an Aurora DB cluster, failover for a DB cluster promotes one of the Aurora Replicas (read-only instances) in the DB cluster to be the primary DB instance (the cluster writer).

For a Multi-AZ DB cluster, after RDS terminates the primary DB instance, the internal monitoring system detects that the primary DB instance is unhealthy and promotes a readable standby (read-only instances) in the DB cluster to be the primary DB instance (the cluster writer). Failover times are typically less than 35 seconds.

An Amazon Aurora DB cluster automatically fails over to an Aurora Replica, if one exists, when the primary DB instance fails. A Multi-AZ DB cluster automatically fails over to a readable standby DB instance when the primary DB instance fails.

To simulate a failure of a primary instance for testing, you can force a failover. Because each instance in a DB cluster has its own endpoint address, make sure to clean up and re-establish any existing connections that use those endpoint addresses when the failover is complete.

For more information on Amazon Aurora DB clusters, see What is Amazon Aurora? in the Amazon Aurora User Guide.

For more information on Multi-AZ DB clusters, see Multi-AZ DB cluster deployments in the Amazon RDS User Guide.

Implementations§

Source§

impl FailoverDBClusterFluentBuilder

Source

pub fn as_input(&self) -> &FailoverDbClusterInputBuilder

Access the FailoverDBCluster as a reference.

Source

pub async fn send( self, ) -> Result<FailoverDbClusterOutput, SdkError<FailoverDBClusterError, HttpResponse>>

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.

Source

pub fn customize( self, ) -> CustomizableOperation<FailoverDbClusterOutput, FailoverDBClusterError, Self>

Consumes this builder, creating a customizable operation that can be modified before being sent.

Source

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

The identifier of the DB cluster to force a failover for. This parameter isn't case-sensitive.

Constraints:

  • Must match the identifier of an existing DB cluster.

Source

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

The identifier of the DB cluster to force a failover for. This parameter isn't case-sensitive.

Constraints:

  • Must match the identifier of an existing DB cluster.

Source

pub fn get_db_cluster_identifier(&self) -> &Option<String>

The identifier of the DB cluster to force a failover for. This parameter isn't case-sensitive.

Constraints:

  • Must match the identifier of an existing DB cluster.

Source

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

The name of the DB instance to promote to the primary DB instance.

Specify the DB instance identifier for an Aurora Replica or a Multi-AZ readable standby in the DB cluster, for example mydbcluster-replica1.

This setting isn't supported for RDS for MySQL Multi-AZ DB clusters.

Source

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

The name of the DB instance to promote to the primary DB instance.

Specify the DB instance identifier for an Aurora Replica or a Multi-AZ readable standby in the DB cluster, for example mydbcluster-replica1.

This setting isn't supported for RDS for MySQL Multi-AZ DB clusters.

Source
