The ladder backend is ported to Java. After integration testing the development environment during the past few days, I feel confident enough to go live with the new backend. 1, 2, 3 live!
Players shouldn’t recognize the switch (except maybe a slightly improved performance).
Although the whole thing is written test-driven with a coverage of 93% percent and the fact that I manually tested each usecase with the current app, there might still be bugs that slipped through.
If you notice anything weird about the ladder backend, I’d be glad if you throw me a message!
And the good news: After this being done now, I have time again to add new game content. Yay!
