Properties for DatabaseClusterFromSnapshot.

Parameters:

engine (IClusterEngine) – What kind of database to start.
instance_props (Union[InstanceProps, Dict[str, Any]]) – Settings for the individual instances that are launched.
snapshot_identifier (str) – 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.
backtrack_window (Optional[Duration]) – 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. Default: 0 seconds (no backtrack)
backup (Union[BackupProps, Dict[str, Any], None]) – Backup settings. 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.
cloudwatch_logs_exports (Optional[Sequence[str]]) – The list of log types that need to be enabled for exporting to CloudWatch Logs. Default: - no log exports
cloudwatch_logs_retention (Optional[RetentionDays]) – 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. Default: - logs never expire
cloudwatch_logs_retention_role (Optional[IRole]) – The IAM role for the Lambda function associated with the custom resource that sets the retention policy. Default: - a new role is created.

iam_authentication (Optional[bool]) – Whether to enable mapping of AWS Identity and Access Management (IAM) accounts to database accounts. Default: false
instance_identifier_base (Optional[str]) – Base identifier for instances. Every replica is named by appending the replica number to this string, 1-based. Default: - clusterIdentifier is used with the word “Instance” appended. If clusterIdentifier is not provided, the identifier is automatically generated.

port (Union[int, float, None]) – What port to listen on. Default: - The default for the engine is used.
preferred_maintenance_window (Optional[str]) – A preferred maintenance window day/time range. Should be specified as a range ddd:hh24:mi-ddd:hh24:mi (24H Clock UTC).

s3_export_role (Optional[IRole]) – Role that will be associated with this DB cluster to enable S3 export. This feature is only supported by the Aurora database engine. This property must not be used if s3ExportBuckets is used. For MySQL: Default: - New role is created if s3ExportBuckets is set, no role is defined otherwise
s3_import_buckets (Optional[Sequence[IBucket]]) – S3 buckets that you want to load data from. This feature is only supported by the Aurora database engine. This property must not be used if s3ImportRole is used. For MySQL: Default: - None
s3_import_role (Optional[IRole]) – Role that will be associated with this DB cluster to enable S3 import. This feature is only supported by the Aurora database engine.
