This paragraph summarizes the text: David Bailey, an intern at the Wendelstein 7-X fusion reactor experiment, uses TimescaleDB to monitor the reliability of the reactor's heating system. He collects and handles various types of data using TimescaleDB, including general health metrics, log messages, and detection events. The database provides a well-balanced mixture of features, being built on top of PostgreSQL while still giving access to regular relational database features. David uses Grafana extensively to plot the measurements with just a few SQL queries, which would have been much harder without it. He is motivated to share his experience with others in his field and wants to motivate his research institute to install a proper multi-node TimescaleDB cluster.
