By "lots of state" I don't think he meant "lots of data", but rather data that get changed a lot: Q&A forum, CRUD application, etc.

Functional paradigms can still be used (e.g. HackerNews, though let's be honest...I love it but it's not the most challenging feature set). But FP isn't as natural of a fit as the problems chosen to introduce it.

Not saying your wrong about what he meant, but Spark can also keep state across the Cluster, not just data. Check out the "UpdateStateByKey Operation" in the following page.
