We run into limits while trying to run this test suite, and try to work around that in different ways. It would be extremely useful to possibly run the tests in parts. But I'm not sure how we could split this up. We could either split this into multiple projects if there is a good logical boundary for that. Or we could pick handful of big classes, and explicitly run them in a separate helix job.
cc @kg @pavelsavara for more details on the issues we are running into.
