Annotation Type DynamoDbUpdateBehavior

@Target(METHOD) @Retention(RUNTIME) public @interface DynamoDbUpdateBehavior
Specifies the behavior when this attribute is updated as part of an 'update' operation such as UpdateItem. See documentation of UpdateBehavior for details on the different behaviors supported and the default behavior. For attributes within nested objects, this annotation is only respected when the request uses IgnoreNullsMode.SCALAR_ONLY. In IgnoreNullsMode.MAPS_ONLY or IgnoreNullsMode.DEFAULT, the annotation has no effect. When applied to a list of nested objects, the annotation is not supported, as individual elements cannot be updated — the entire list is replaced during an update operation.
