Type: *bool

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 the EnableIAMDatabaseAuthentication, MasterUserPassword, and NewDBClusterIdentifier values. If you set the ApplyImmediately parameter value to false, then changes to the EnableIAMDatabaseAuthentication, MasterUserPassword, and 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: *int64

The target backtrack window, in seconds. To disable backtracking, set this value to 0.

Default: 0


  • If specified, this value must be set to a number from 0 to 259,200 (72 hours).


Type: *int64

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

Default: 1


  • Must be a value from 1 to 35


The configuration setting for the log types to be enabled for export to CloudWatch Logs for a specific DB instance or DB cluster.

The EnableLogTypes and DisableLogTypes arrays determine which logs will be exported (or not exported) to CloudWatch Logs. The values within these arrays depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs ( in the Amazon RDS User Guide.


Type: *string

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


  • Must match the identifier of an existing DBCluster.

DBClusterIdentifier is a required field


Type: *string

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


Type: *bool

Indicates if the DB cluster has deletion protection enabled. The database can't be deleted when this value is set to true.


Type: *bool

HTTP endpoint functionality is in beta for Aurora Serverless and is subject to change.

A value that indicates whether to enable the HTTP endpoint for an Aurora Serverless DB cluster. By default, the HTTP endpoint is disabled.

When enabled, the HTTP endpoint provides a connectionless web service API for running SQL queries on the Aurora Serverless DB cluster. You can also query your database from inside the RDS console with the query editor.

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


Type: *bool

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

Default: false


Type: *string

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 CreateDBCluster, or call DescribeDBEngineVersions.


Type: *string

The new password for the master database user. This password can contain any printable ASCII character except "/", """, or "@".

Constraints: Must contain from 8 to 41 characters.


Type: *string

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


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

  • The first character must be a letter

  • Can't end with a hyphen or contain two consecutive hyphens

Example: my-cluster2


Type: *string

A value that indicates that the DB cluster should be associated with the specified option group. Changing this parameter doesn't result in an outage except in the following case, and the change is applied during the next maintenance window unless the ApplyImmediately parameter is set to true for this request. If the parameter change results in an option group that enables OEM, this change can cause a brief (sub-second) period during which new connections are rejected but existing connections are not interrupted.

Permanent options can't be removed from an option group. The option group can't be removed from a DB cluster once it is associated with a DB cluster.


Type: *int64

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: *string

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 AWS Region. To see the time blocks available, see Adjusting the Preferred DB Cluster Maintenance Window ( in the Amazon Aurora User Guide.


  • 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

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 AWS Region, occurring on a random day of the week. To see the time blocks available, see Adjusting the Preferred DB Cluster Maintenance Window ( in the Amazon Aurora User Guide.

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

Constraints: Minimum 30-minute window.


Contains the scaling configuration of an Aurora Serverless DB cluster.

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