Properties

AutoMinorVersionUpgrade

This parameter does not apply to Amazon DocumentDB. Amazon DocumentDB does not perform minor version upgrades regardless of the value set.

Default: false

Required: No

Type: Boolean

Required: No

Type: Boolean

Update requires: No interruption

DBClusterIdentifier

The identifier of the cluster that the instance will belong to.

Required: Yes
