Creates a new Amazon Aurora DB cluster.

You can use the ReplicationSourceIdentifier parameter to create the DB cluster as a read replica of another DB cluster or Amazon RDS MySQL DB instance. For cross-region replication where the DB cluster identified by ReplicationSourceIdentifier is encrypted, you must also specify the PreSignedUrl parameter.

For more information on Amazon Aurora, see What Is Amazon Aurora? in the Amazon Aurora User Guide.

Parameter dBClusterIdentifier : The DB cluster identifier. This parameter is stored as a lowercase string.

Constraints:

  • Must contain from 1 to 63 letters, numbers, or hyphens.
  • First character must be a letter.
  • Can't end with a hyphen or contain two consecutive hyphens.
Example: my-cluster1

Parameter engine : The name of the database engine to be used for this DB cluster.

Valid Values: aurora (for MySQL 5.6-compatible Aurora), aurora-mysql (for MySQL 5.7-compatible Aurora), and aurora-postgresql

Parameter availabilityZones : A list of Availability Zones (AZs) where instances in the DB cluster can be created. For information on AWS Regions and Availability Zones, see Choosing the Regions and Availability Zones in the Amazon Aurora User Guide.

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

Constraints:

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

Parameter backupRetentionPeriod : The number of days for which automated backups are retained.

Default: 1

Constraints:

  • Must be a value from 1 to 35

Parameter characterSetName : A value that indicates that the DB cluster should be associated with the specified CharacterSet.

Parameter copyTagsToSnapshot : A value that indicates whether to copy all tags from the DB cluster to snapshots of the DB cluster. The default is not to copy them.

Parameter dBClusterParameterGroupName : The name of the DB cluster parameter group to associate with this DB cluster. If you do not specify a value, then the default DB cluster parameter group for the specified DB engine and version is used.

Constraints:

  • If supplied, must match the name of an existing DB cluster parameter group.

Parameter dBSubnetGroupName : A DB subnet group to associate with this DB cluster.

Constraints: Must match the name of an existing DBSubnetGroup. Must not be default.

Example: mySubnetgroup

Parameter databaseName : The name for your database of up to 64 alphanumeric characters. If you do not provide a name, Amazon RDS doesn't create a database in the DB cluster you are creating.

Parameter 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.

Parameter domain : The Active Directory directory ID to create the DB cluster in.

For Amazon Aurora DB clusters, Amazon RDS can use Kerberos Authentication to authenticate users that connect to the DB cluster. For more information, see Kerberos Authentication in the Amazon Aurora User Guide.

Parameter domainIAMRoleName : Specify the name of the IAM role to be used when making API calls to the Directory Service.

Parameter enableCloudwatchLogsExports : The list of log types that need to be enabled for exporting to CloudWatch Logs. The values in the list depend on the DB engine being used. For more information, see Publishing Database Logs to Amazon CloudWatch Logs in the Amazon Aurora User Guide.

Aurora MySQL

Possible values are audit, error, general, and slowquery.

Aurora PostgreSQL

Possible values are postgresql and upgrade.

Parameter enableGlobalWriteForwarding : A value that indicates whether to enable write operations to be forwarded from this cluster to the primary cluster in an Aurora global database. The resulting changes are replicated back to this cluster. This parameter only applies to DB clusters that are secondary clusters in an Aurora global database. By default, Aurora disallows write operations for secondary clusters.

Parameter enableHttpEndpoint : 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, see Using the Data API for Aurora Serverless in the Amazon Aurora User Guide.

Parameter enableIAMDatabaseAuthentication : A value that indicates whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. By default, mapping is disabled.

For more information, see IAM Database Authentication in the Amazon Aurora User Guide.

Parameter engineMode : The DB engine mode of the DB cluster, either provisioned serverless, parallelquery, global, or multimaster.

The parallelquery engine mode isn't required for Aurora MySQL version 1.23 and higher 1.x versions, and version 2.09 and higher 2.x versions.

The global engine mode isn't required for Aurora MySQL version 1.22 and higher 1.x versions, and global engine mode isn't required for any 2.x versions.

The multimaster engine mode only applies for DB clusters created with Aurora MySQL version 5.6.10a.

For Aurora PostgreSQL, the global engine mode isn't required, and both the parallelquery and the multimaster engine modes currently aren't supported.

Limitations and requirements apply to some DB engine modes. For more information, see the following sections in the Amazon Aurora User Guide:

Parameter engineVersion : The version number of the database engine to use.

To list all of the available engine versions for aurora (for MySQL 5.6-compatible Aurora), use the following command:

aws rds describe-db-engine-versions --engine aurora --query "DBEngineVersions[].EngineVersion"

To list all of the available engine versions for aurora-mysql (for MySQL 5.7-compatible Aurora), use the following command:

aws rds describe-db-engine-versions --engine aurora-mysql --query "DBEngineVersions[].EngineVersion"

To list all of the available engine versions for aurora-postgresql, use the following command:

aws rds describe-db-engine-versions --engine aurora-postgresql --query "DBEngineVersions[].EngineVersion"

Aurora MySQL

Example: 5.6.10a, 5.6.mysql_aurora.1.19.2, 5.7.12, 5.7.mysql_aurora.2.04.5

Aurora PostgreSQL

Example: 9.6.3, 10.7

Parameter globalClusterIdentifier : The global cluster ID of an Aurora cluster that becomes the primary cluster in the new global database cluster.

Parameter kmsKeyId : The AWS KMS key identifier for an encrypted DB cluster.

The AWS KMS key identifier is the key ARN, key ID, alias ARN, or alias name for the AWS KMS customer master key (CMK). To use a CMK in a different AWS account, specify the key ARN or alias ARN.

When a CMK isn't specified in KmsKeyId:

  • If ReplicationSourceIdentifier identifies an encrypted source, then Amazon RDS will use the CMK used to encrypt the source. Otherwise, Amazon RDS will use your default CMK.
  • If the StorageEncrypted parameter is enabled and ReplicationSourceIdentifier isn't specified, then Amazon RDS will use your default CMK.
There is a default CMK for your AWS account. Your AWS account has a different default CMK for each AWS Region.

If you create a read replica of an encrypted DB cluster in another AWS Region, you must set KmsKeyId to a AWS KMS key identifier that is valid in the destination AWS Region. This CMK is used to encrypt the read replica in that AWS Region.

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

Constraints: Must contain from 8 to 41 characters.

Parameter masterUsername : The name of the master user for the DB cluster.

Constraints:

  • Must be 1 to 16 letters or numbers.
  • First character must be a letter.
  • Can't be a reserved word for the chosen database engine.

Parameter optionGroupName : A value that indicates that the DB cluster should be associated with the specified option group.

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.

Parameter port : The port number on which the instances in the DB cluster accept connections.

Default: 3306 if engine is set as aurora or 5432 if set to aurora-postgresql.

Parameter preSignedUrl : A URL that contains a Signature Version 4 signed request for the CreateDBCluster action to be called in the source AWS Region where the DB cluster is replicated from. You only need to specify PreSignedUrl when you are performing cross-region replication from an encrypted DB cluster.

The pre-signed URL must be a valid request for the CreateDBCluster API action that can be executed in the source AWS Region that contains the encrypted DB cluster to be copied.

The pre-signed URL request must contain the following parameter values:

  • KmsKeyId - The AWS KMS key identifier for the key to use to encrypt the copy of the DB cluster in the destination AWS Region. This should refer to the same AWS KMS CMK for both the CreateDBCluster action that is called in the destination AWS Region, and the action contained in the pre-signed URL.
  • DestinationRegion - The name of the AWS Region that Aurora read replica will be created in.
  • ReplicationSourceIdentifier - The DB cluster identifier for the encrypted DB cluster to be copied. This identifier must be in the Amazon Resource Name (ARN) format for the source AWS Region. For example, if you are copying an encrypted DB cluster from the us-west-2 AWS Region, then your ReplicationSourceIdentifier would look like Example: arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1.
To learn how to generate a Signature Version 4 signed request, see Authenticating Requests: Using Query Parameters (AWS Signature Version 4) and Signature Version 4 Signing Process.

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

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.

Parameter 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 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.

Parameter replicationSourceIdentifier : The Amazon Resource Name (ARN) of the source DB instance or DB cluster if this DB cluster is created as a read replica.

Parameter scalingConfiguration : For DB clusters in serverless DB engine mode, the scaling properties of the DB cluster.

Parameter sourceRegion : The ID of the region that contains the source for the read replica.

Parameter storageEncrypted : A value that indicates whether the DB cluster is encrypted.

Parameter tags : Tags to assign to the DB cluster.

Parameter vpcSecurityGroupIds : A list of EC2 VPC security groups to associate with this DB cluster.
