	DBInstanceIdentifier *string

	// Specifies whether the modifications in this request and any pending

	// Example: mydbinstance

	// DocumentDB uses your default KMS key. There is a default KMS key for your Amazon
	// Web Services account. Your Amazon Web Services account has a different default
	// KMS key for each Amazon Web Services region.
	PerformanceInsightsKMSKeyId *string

	// The weekly time range (in UTC) during which system maintenance can occur, which
	// might result in an outage. Changing this parameter doesn't result in an outage

	// soon as possible. If there are pending actions that cause a reboot, and the
	// maintenance window is changed to include the current time, changing this
	// parameter causes a reboot of the instance. If you are moving this window to the
	// current time, there must be at least 30 minutes between the current time and end
	// of the window to ensure that pending changes are applied. Default: Uses existing
	// setting. Format: ddd:hh24:mi-ddd:hh24:mi Valid days: Mon, Tue, Wed, Thu, Fri,
	// Sat, Sun Constraints: Must be at least 30 minutes.
	PreferredMaintenanceWindow *string

	// instance. Default: 1 Valid values: 0-15
