You can use it on your smartphone to know whether it’s going to rain tomorrow, on smart home devices that will play music for you (hey, Alexa!), and some countries are even making the most of it to build smart cities and speed up vehicle control. Time-series data is everywhere and helps you track changes over time, allowing you to understand what, why, and when something happened. As more and more applications are built on it, the need to manage, store, and analyze that timestamped information swiftly and efficiently is increasing for developers and data scientists worldwide. The open-source relational database TimescaleDB is designed specifically for handling time-series data, offering features such as real-time availability, forecasting capabilities, and graphing options, making it an ideal solution for managing and analyzing large amounts of timestamped information.
