Update MongoDB $jsonSchema with Spring Data

Spring Data documentation describes how to create collection with given $jsonSchema, and how to perform a validation query.

Is there a way to update $jsonSchema for an existing collection? MongoTemplate.createCollection() for an existing one results in MongoCommandException with error code 48 (collection exists), schema is not being updated.

Ok, looks like there is no ready-to-use method in Spring Data, but it is pretty simple to implement: 

<T> void updateSchema(MongoTemplate template, Class<T> entityClazz, MongoJsonSchema schema) {
    template.executeCommand(new Document(Map.of(
            "collMod", template.getCollectionName(entityClazz),
            "validator", schema.toDocument()
    )));
}

Also keep in mind that default readWrite role is not enough, user needs to have collMod privilege.
