The database is usually the heart of a software system. And there are many database technologies that we can pick from. In this talk, we’ll explore where RDBMS and NoSQL fall short and how NewSQL fills the gap. We’ll see what types of NewSQL databases exist and how they work. And we’ll also go over different NewSQL solutions that we can pick for our projects. By the end of the talk, we’ll have a good understanding of when and how to apply a NewSQL database in our big scale applications.
