> The only way to support delete statements right now is to implement \{{SupportsDelete}}. According to its Javadoc, that interface is meant for cases when we can delete data without much effort (e.g. like deleting a complete partition in a Hive table). It is clear we need a more sophisticated API for row-level deletes. That's why it would be beneficial to add a method to \{{SupportsDelete}} so that Spark can check if a source can easily delete data with just having filters or it will need a full rewrite later on. This way, we have more control in the future.
