My memory is fading years after leaving FB, but I don't believe "one table" is correct at all. As far as I can recall, UDB's design permits (but does not require) each object type to have its own table; ditto for association types. I believe different object tables have the same structure / flexible serialization strategy, but the important ones are each distinct tables within a shard.
