Sensors post readings to it, a dashboard on the same network shows the latest value per device, and someone asks about history: averages, peaks, the hour a fridge ran warm. The gateway is often a small box with no room for a database team, so it should be one program and one file.</p> <p>This case study runs that set-up with <code>kvsqld</code>. Twenty simulated devices post readings over HTTP on their own connections, while a dashboard reads the latest value by key and asks SQL for history. It&rsquo;s part of <a href="https://github.com/softdevstudio/kvsql/blob/main/crates/kvsql-db/examples/case_studies.rs">case_studies.rs</a> in the repository. The figures are from its recorded run of October 22, 2026, on a real file on a Linux container with two virtual CPUs. The output is in <a href="https://github.com/softdevstudio/kvsql/blob/main/test/results/latest/case-studies.md">case-studies.md</a>.</p>
