newSchemaChangePolicy :: SchemaChangePolicy Source #

Create a value of SchemaChangePolicy with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

$sel:deleteBehavior:SchemaChangePolicy', schemaChangePolicy_deleteBehavior - The deletion behavior when the crawler finds a deleted object.

$sel:updateBehavior:SchemaChangePolicy', schemaChangePolicy_updateBehavior - The update behavior when the crawler finds a changed schema.

schemaChangePolicy_deleteBehavior :: Lens' SchemaChangePolicy (Maybe DeleteBehavior) Source #

The deletion behavior when the crawler finds a deleted object.

schemaChangePolicy_updateBehavior :: Lens' SchemaChangePolicy (Maybe UpdateBehavior) Source #

The update behavior when the crawler finds a changed schema.
