We released Stroppy v6.0.0. This is the largest change we have made to the project so far: Stroppy is now a single Go binary with its own workload engine, typed parameters, native metrics, and Go implementations of every built-in workload.
Stroppy v5 was a k6 extension. Stroppy v6 is not.
We did not make that change because k6 is a poor load-testing tool. k6 gave us virtual users, scenarios, metrics, reporting, and a JavaScript runtime when Stroppy was much smaller. It helped us reach a working multi-database benchmark faster than building every subsystem ourselves.
The problem was fit. As Stroppy became a database benchmark rather than a thin extension, we used less of what k6 was built to provide and added more adapters around the parts we did use. Eventually the adapter layer became the product.
