ModifyDBCluster - Amazon Neptune

ModifyDBCluster

Modify a setting for a DB cluster. You can change one or more database configuration parameters by specifying these parameters and the new values in the request.

Request Parameters

For information about the parameters that are common to all actions, see Common Parameters.

AllowMajorVersionUpgrade

A value that indicates whether upgrades between different major versions are allowed.

Constraints: You must set the allow-major-version-upgrade flag when providing an EngineVersion parameter that uses a different major version than the DB cluster's current version.

Type: Boolean

Required: No

ApplyImmediately

A value that specifies whether the modifications in this request and any pending modifications are asynchronously applied as soon as possible, regardless of the PreferredMaintenanceWindow setting for the DB cluster. If this parameter is set to false, changes to the DB cluster are applied during the next maintenance window.

The ApplyImmediately parameter only affects NewDBClusterIdentifier values. If you set the ApplyImmediately parameter value to false, then changes to NewDBClusterIdentifier values are applied during the next maintenance window. All other changes are applied immediately, regardless of the value of the ApplyImmediately parameter.

Default: false

Type: Boolean

Required: No

BackupRetentionPeriod

The number of days for which automated backups are retained. You must specify a minimum value of 1.

Default: 1

Constraints:

  • Must be a value from 1 to 35

Type: Integer

Required: No

CloudwatchLogsExportConfiguration

The configuration setting for the log types to be enabled for export to CloudWatch Logs for a specific DB cluster. See Using the CLI to publish Neptune audit logs to CloudWatch Logs.

Type: CloudwatchLogsExportConfiguration object

Required: No

CopyTagsToSnapshot

If set to true, tags are copied to any snapshot of the DB cluster that is created.

Type: Boolean

Required: No

DBClusterIdentifier

The DB cluster identifier for the cluster being modified. This parameter is not case-sensitive.

Constraints:

  • Must match the identifier of an existing DBCluster.

Type: String

Required: Yes

DBClusterParameterGroupName

The name of the DB cluster parameter group to use for the DB cluster.

Type: String

Required: No

DBInstanceParameterGroupName

The name of the DB parameter group to apply to all instances of the DB cluster.

Note

When you apply a parameter group using DBInstanceParameterGroupName, parameter changes aren't applied during the next maintenance window but instead are applied immediately.

Default: The existing name setting

Constraints:

  • The DB parameter group must be in the same DB parameter group family as the target DB cluster version.

  • The DBInstanceParameterGroupName parameter is only valid in combination with the AllowMajorVersionUpgrade parameter.

Type: String

Required: No

DeletionProtection

A value that indicates whether the DB cluster has deletion protection enabled. The database can't be deleted when deletion protection is enabled. By default, deletion protection is disabled.

Type: Boolean

Required: No

EnableIAMDatabaseAuthentication

True to enable mapping of Amazon Identity and Access Management (IAM) accounts to database accounts, and otherwise false.

Default: false

Type: Boolean

Required: No

EngineVersion

The version number of the database engine to which you want to upgrade. Changing this parameter results in an outage. The change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true.

For a list of valid engine versions, see Engine Releases for Amazon Neptune, or call DescribeDBEngineVersions.

Type: String

Required: No

MasterUserPassword

Not supported by Neptune.

Type: String

Required: No

NewDBClusterIdentifier

The new DB cluster identifier for the DB cluster when renaming a DB cluster. This value is stored as a lowercase string.

Constraints:

  • Must contain from 1 to 63 letters, numbers, or hyphens

  • The first character must be a letter

  • Cannot end with a hyphen or contain two consecutive hyphens

Example: my-cluster2

Type: String

Required: No

OptionGroupName

Not supported by Neptune.

Type: String

Required: No

Port

The port number on which the DB cluster accepts connections.

Constraints: Value must be 1150-65535

Default: The same port as the original DB cluster.

Type: Integer

Required: No

PreferredBackupWindow

The daily time range during which automated backups are created if automated backups are enabled, using the BackupRetentionPeriod parameter.

The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Region.

Constraints:

  • Must be in the format hh24:mi-hh24:mi.

  • Must be in Universal Coordinated Time (UTC).

  • Must not conflict with the preferred maintenance window.

  • Must be at least 30 minutes.

Type: String

Required: No

PreferredMaintenanceWindow

The weekly time range during which system maintenance can occur, in Universal Coordinated Time (UTC).

Format: ddd:hh24:mi-ddd:hh24:mi

The default is a 30-minute window selected at random from an 8-hour block of time for each Amazon Region, occurring on a random day of the week.

Valid Days: Mon, Tue, Wed, Thu, Fri, Sat, Sun.

Constraints: Minimum 30-minute window.

Type: String

Required: No

ServerlessV2ScalingConfiguration

Contains the scaling configuration of a Neptune Serverless DB cluster.

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

Type: ServerlessV2ScalingConfiguration object

Required: No

StorageType

The storage type to associate with the DB cluster.

Valid Values:

  • standard   –   ( the default ) Configures cost-effective database storage for applications with moderate to small I/O usage.

  • iopt1   –   Enables I/O-Optimized storage that's designed to meet the needs of I/O-intensive graph workloads that require predictable pricing with low I/O latency and consistent I/O throughput.

    Neptune I/O-Optimized storage is only available starting with engine release 1.3.0.0.

Type: String

Required: No

VpcSecurityGroupIds.VpcSecurityGroupId.N

A list of VPC security groups that the DB cluster will belong to.

Type: Array of strings

Required: No

Response Elements

The following element is returned by the service.

DBCluster
