Hi Jacek, The unit tests are from the company I work at, so I cannot share any link. They repeatedly create and drop schemas as part of the unit test setup and teardown methods.
If it helps, I can provide minimal executable examples, but I thought maybe the problem is already known (after all, I guess some Cassandra developers are using macOS)?
