Summary
This chapter is indeed full of concepts, code, and execution. I am sure if you are reading this summary, you have got something out of this chapter. We have learned the concept of Polyglot Persistence and how we can develop it using RethinkDB. I hope it's helpful to you.
In next and last chapter, we are going to learn an amazing framework made by the RethinkDB team called Horizon. Horizon is the framework which gives you a ready-made middle-layer along with the database so that you can code your web/mobile app in blazing fast speed.
