I think it would be great to also have integration tests that makes it easy to replicate certain scenarios. Added some simple ones, but we can extend by having two tables that modify a different partition etc.

Thanks @hussein-awala for jumping in here. And that's correct, once the optimistic concurrency control has been added, they should start passing (for snapshot isolation, not for serializable isolation). I've added a comment, LMKWYT

I think it would be great to also have integration tests that make it
easy to replicate certain scenarios.
Added some simple ones, but we can extend by having two tables that
modify a different partition etc.
