Getting started with InfluxDB with Python and MQTT (RabbitMQ)

Real time applications is a very hot topic right now, especially for Internet of Things, which is one of the biggest emerging tech industries. Real time Big Data are very important in other industries as well such as FinTech, InsurTech and the Automotive industry. I wanted to familiarize myself with these technologies and real-time applications in general, from the software/Cloud infrastructure perspective, and that’s why I decided to start this simple project to learn InfluxDB, a time-series database, and MQTT, a message based communication protocol. Time series DBs and the MQTT protocol are widely used in IoT solutions and real-time applications. I will also create a simple python script which will send (publish) some financial data which will then be stored and visualized in InfluxDB.

Setting up the MQTT broker

We will first start by setting up a RabbitMQ server which is a message broker and also supports the MQTT protocol.

The fastest and easiest way to download, setup and run these is with Docker and Docker compose. If you haven’t installed these already, I totally recommend you to. Trust me it will be very handy for your future projects as well. Check out…
