updateKeyspace method

Future<UpdateKeyspaceResponse> updateKeyspace({ required String keyspaceName, required ReplicationSpecification replicationSpecification, ClientSideTimestamps? clientSideTimestamps, })

Adds a new Amazon Web Services Region to the keyspace. You can add a new Region to a keyspace that is either a single or a multi-Region keyspace. Amazon Keyspaces is going to replicate all tables in the keyspace to the new Region. To successfully replicate all tables to the new Region, they must use client-side timestamps for conflict resolution. To enable client-side timestamps, specify clientSideTimestamps.status = enabled when invoking the API. For more information about client-side timestamps, see Client-side timestamps in Amazon Keyspaces in the Amazon Keyspaces Developer Guide.

To add a Region to a keyspace using the UpdateKeyspace API, the IAM principal needs permissions for the following IAM actions:

• cassandra:Alter
• cassandra:AlterMultiRegionResource
• cassandra:Create
• cassandra:CreateMultiRegionResource
• cassandra:Select
• cassandra:SelectMultiRegionResource
• cassandra:Modify
• cassandra:ModifyMultiRegionResource

If the keyspace contains a table that is configured in provisioned mode with auto scaling enabled, the following additional IAM actions need to be allowed.

• application-autoscaling:RegisterScalableTarget
• application-autoscaling:DeregisterScalableTarget
• application-autoscaling:DescribeScalableTargets
• application-autoscaling:PutScalingPolicy
• application-autoscaling:DescribeScalingPolicies

To use the UpdateKeyspace API, the IAM principal also needs permissions to create a service-linked role with the following elements:

• iam:CreateServiceLinkedRole - The action the principal can perform.
• arn:aws:iam::*:role/aws-service-role/replication.cassandra.amazonaws.com/AWSServiceRoleForKeyspacesReplication - The resource that the action can be performed on.
• iam:AWSServiceName: replication.cassandra.amazonaws.com - The only Amazon Web Services service that this role can be attached to is Amazon Keyspaces.

For more information, see Configure the IAM permissions required to add an Amazon Web Services Region to a keyspace in the Amazon Keyspaces Developer Guide.

May throw AccessDeniedException. May throw ConflictException. May throw InternalServerException. May throw ResourceNotFoundException. May throw ServiceQuotaExceededException. May throw ValidationException.

Parameter keyspaceName : The name of the keyspace.

Implementation

Future<UpdateKeyspaceResponse> updateKeyspace({
  required String keyspaceName,
  required ReplicationSpecification replicationSpecification,
  ClientSideTimestamps? clientSideTimestamps,
}) async {
  final headers = <String, String>{
    'Content-Type': 'application/x-amz-json-1.0',
    'X-Amz-Target': 'KeyspacesService.UpdateKeyspace'
  };
  final jsonResponse = await _protocol.send(
    method: 'POST',
    requestUri: '/',
    exceptionFnMap: _exceptionFns,
    // TODO queryParams
    headers: headers,
    payload: {
      'keyspaceName': keyspaceName,
      'replicationSpecification': replicationSpecification,
      if (clientSideTimestamps != null)
        'clientSideTimestamps': clientSideTimestamps,
    },
  );

  return UpdateKeyspaceResponse.fromJson(jsonResponse.body);
