Options

--db-cluster-identifier (string)

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

Constraints:

  • Must be the identifier for an existing DB cluster.
  • Must contain from 1 to 63 alphanumeric characters or hyphens.
  • First character must be a letter.
  • Cannot end with a hyphen or contain two consecutive hyphens.

--new-db-cluster-identifier (string)

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 alphanumeric characters or hyphens
  • First character must be a letter
  • Cannot end with a hyphen or contain two consecutive hyphens

Example: my-cluster2

--apply-immediately | --no-apply-immediately (boolean)

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

Default: false

--backup-retention-period (integer)

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

--db-cluster-parameter-group-name (string)

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

--vpc-security-group-ids (list)

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

Syntax:

"string" "string" ...

--port (integer)

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.

--master-user-password (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.

--option-group-name (string)

A value that indicates that the DB cluster should be associated with the specified option group. Changing this parameter does not 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 cannot be removed from an option group. The option group cannot be removed from a DB cluster once it is associated with a DB cluster.

--preferred-backup-window (string)

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

Default: A 30-minute window selected at random from an 8-hour block of time per AWS Region. To see the time blocks available, see Adjusting the Preferred Maintenance Window in the Amazon RDS User Guide.

Constraints:

  • Must be in the format hh24:mi-hh24:mi .
  • Times should be in Universal Coordinated Time (UTC).
  • Must not conflict with the preferred maintenance window.
  • Must be at least 30 minutes.

--preferred-maintenance-window (string)

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

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

Default: A 30-minute window selected at random from an 8-hour block of time per AWS Region, occurring on a random day of the week. To see the time blocks available, see Adjusting the Preferred Maintenance Window in the Amazon RDS User Guide.

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

Constraints: Minimum 30-minute window.

--enable-iam-database-authentication | --no-enable-iam-database-authentication (boolean)

A apply-immediately value that is true to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts, and otherwise false.

Default: false

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

DBCluster -> (structure)

Contains the result of a successful invocation of the following actions:

  • create-db-cluster
  • delete-db-cluster
  • failover-db-cluster
  • modify-db-cluster
  • restore-db-cluster-from-snapshot
  • restore-db-cluster-to-point-in-time

This data type is used as a response element in the describe-db-clusters action.

AllocatedStorage -> (integer)

For all database engines except Amazon Aurora, AllocatedStorage specifies the allocated storage size in gigabytes (GB). For Aurora, AllocatedStorage always returns 1, because Aurora DB cluster storage size is not fixed, but instead automatically adjusts as needed.

AvailabilityZones -> (list)

Provides the list of EC2 Availability Zones that instances in the DB cluster can be created in.

(string)

BackupRetentionPeriod -> (integer)

Specifies the number of days for which automatic DB snapshots are retained.

CharacterSetName -> (string)

If present, specifies the name of the character set that this cluster is associated with.

DatabaseName -> (string)

Contains the name of the initial database of this DB cluster that was provided at create time, if one was specified when the DB cluster was created. This same name is returned for the life of the DB cluster.

DBClusterIdentifier -> (string)

Contains a user-supplied DB cluster identifier. This identifier is the unique key that identifies a DB cluster.

DBClusterParameterGroup -> (string)

Specifies the name of the DB cluster parameter group for the DB cluster.

DBSubnetGroup -> (string)

Specifies information on the subnet group associated with the DB cluster, including the name, description, and subnets in the subnet group.

Status -> (string)

Specifies the current state of this DB cluster.

PercentProgress -> (string)

Specifies the progress of the operation as a percentage.

EarliestRestorableTime -> (timestamp)

Specifies the earliest time to which a database can be restored with point-in-time restore.

Endpoint -> (string)

Specifies the connection endpoint for the primary instance of the DB cluster.

ReaderEndpoint -> (string)

The reader endpoint for the DB cluster. The reader endpoint for a DB cluster load-balances connections across the Aurora Replicas that are available in a DB cluster. As clients request new connections to the reader endpoint, Aurora distributes the connection requests among the Aurora Replicas in the DB cluster. This functionality can help balance your read workload across multiple Aurora Replicas in your DB cluster.

If a failover occurs, and the Aurora Replica that you are connected to is promoted to be the primary instance, your connection will be dropped. To continue sending your read workload to other Aurora Replicas in the cluster, you can then reconnect to the reader endpoint.

Specifies whether the DB cluster has instances in multiple Availability Zones.

Engine -> (string)

Provides the name of the database engine to be used for this DB cluster.

EngineVersion -> (string)

Indicates the database engine version.
