What feature(s) are you requesting?

I'd like to see tableName and modType added to the attributes in PubSub. Messages of subscriptions in Cloud PubSub can only be filtered by attributes. However, in the current implementation, there are no attributes(null) in the PubSub Messages and there are no ways to filter the message by tableName or modType.
