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.
