Chapter 11. Let Us Store the Data
We are living in the age of data. It is everywhere. Everybody is generating it and everything is generating it. Twitter, Instagram, Facebook, IoT devices, Industrial IoT devices, sensors, gaming consoles, web applications, stock trading, you name it. And on top of that, things are also getting connected to each other. But the real question is, "Where do we store this data and how shall we store this data?" It is not a simple question to answer, as we will learn in this chapter.
In this chapter, we will discuss following topics:
- The data explosion problem and how traditional relational systems were not meant for handling such huge amounts of data
- Hadoop and why the industry is crazy about it
- Columnar stores, the use cases they solve and why they are considered worthy of big data storage
- Connected data and the graph stores that enable data to be represented as nodes and edges
