Aside from the problems mentioned below, it's a rare case that tightly coupling your application code directly into your database makes it easier to maintain your codebase, especially as you scale.
If you roll out your custom Cassandra application, then decide you need search, will you also embed elastic search? What if you want to use something that's not written in Java? Communication protocols were written for a reason.
