engine

Type: IClusterEngine

What kind of database to start.


snapshotIdentifier

Type: string

The identifier for the DB instance snapshot or DB cluster snapshot to restore from.

You can use either the name or the Amazon Resource Name (ARN) to specify a DB cluster snapshot. However, you can use only the ARN to specify a DB instance snapshot.


backtrackWindow?

Type: Duration (optional, default: 0 seconds (no backtrack))

The number of seconds to set a cluster's target backtrack window to.

This feature is only supported by the Aurora MySQL database engine and cannot be enabled on existing clusters.

See also: https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/AuroraMySQL.Managing.Backtrack.html


backup?

Type: BackupProps (optional, default: Backup retention period for automated backups is 1 day. Backup preferred window is set to 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.)

Backup settings.

cloudwatchLogsRetention?

Type: RetentionDays (optional, default: logs never expire)

The number of days log events are kept in CloudWatch Logs.

When updating this property, unsetting it doesn't remove the log retention policy. To remove the retention policy, set the value to Infinity.


cloudwatchLogsRetentionRole?

Type: IRole (optional, default: a new role is created.)

The IAM role for the Lambda function associated with the custom resource that sets the retention policy.


clusterIdentifier?

Type: string (optional, default: A name is automatically generated.)

An optional identifier for the cluster.


copyTagsToSnapshot?

Type: boolean (optional, default: true)

Whether to copy tags to the snapshot when a snapshot is created.


credentials?⚠️

⚠️ Deprecated: use snapshotCredentials which allows to generate a new password

Type: Credentials (optional, default: A username of 'admin' (or 'postgres' for PostgreSQL) and SecretsManager-generated password that will not be applied to the cluster, use snapshotCredentials for the correct behavior.)

Credentials for the administrative user.

Note - using this prop only works with Credentials.fromPassword() with the username of the snapshot, Credentials.fromUsername() with the username and password of the snapshot or Credentials.fromSecret() with a secret containing the username and password of the snapshot.


defaultDatabaseName?

Type: string (optional, default: Database is not created in cluster.)

Name of a database which is automatically created inside the cluster.


deletionProtection?

Type: boolean (optional, default: true if removalPolicy is RETAIN, undefined otherwise, which will not enable deletion protection. To disable deletion protection after it has been enabled, you must explicitly set this value to false.)

Indicates whether the DB cluster should have deletion protection enabled.


iamAuthentication?

Type: boolean (optional, default: false)

Whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts.


instanceIdentifierBase?

Type: string (optional, default: clusterIdentifier is used with the word "Instance" appended. If clusterIdentifier is not provided, the identifier is automatically generated.)

Base identifier for instances.

Every replica is named by appending the replica number to this string, 1-based.


instanceProps?⚠️

⚠️ Deprecated: - use writer and readers instead

Type: InstanceProps (optional)

Settings for the individual instances that are launched.


instanceUpdateBehaviour?

Type: InstanceUpdateBehaviour (optional, default: InstanceUpdateBehaviour.BULK)

The ordering of updates for instances.

monitoringInterval?

Type: Duration (optional, default: no enhanced monitoring)

The interval, in seconds, between points when Amazon RDS collects enhanced monitoring metrics for the DB instances.


monitoringRole?

Type: IRole (optional, default: A role is automatically created for you)

Role that will be used to manage DB instances monitoring.


networkType?

Type: NetworkType (optional, default: IPV4)

The network type of the DB instance.


parameterGroup?

Type: IParameterGroup (optional, default: No parameter group.)

Additional parameters to pass to the database engine.


parameters?

Type: { [string]: string } (optional, default: None)

The parameters in the DBClusterParameterGroup to create automatically.

You can only specify parameterGroup or parameters but not both. You need to use a versioned engine to auto-generate a DBClusterParameterGroup.


port?

Type: number (optional, default: The default for the engine is used.)

What port to listen on.


preferredMaintenanceWindow?

Type: string (optional, default: 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.)

A preferred maintenance window day/time range. Should be specified as a range ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC).

Example: 'Sun:23:45-Mon:00:15'
