Summary
In this chapter, you have learned about TSDBs. These are fundamental pieces of any IoT system. They allow you to store streams of data according to the timestamp of each point. Then, you can process, analyze, and visualize the data using Grafana.
We have seen the main concepts related to TSDBs, and two different implementations: InfluxDB and OpenTSDB.
You have learned how to store and read data using these databases.
In this book, we are going to use InfluxDB to show how to implement some examples. InfluxDB is easy to install and use and you can even take advantage of the ready-to-go service provided by InfluxData.
In the next chapter, we will see how to use data from TSDBs for building different types of dashboards.
