Minor Description
The test creates the same tables and views for each test case, drops them between, and recreates them. In addition each test case is doing index upgrades / downgrades which requires disabling tables and rebuilding them. Plus there are a lot of test cases, because of the cross-product of the parameters.
According to achouhan, this is causing some builds to fail with timeouts, and taking 20-30 min for me locally the last time I needed to add a test case. Looks like it's time to refactor this test so it goes faster.
I suspect just having each test case create its own test-specific tables (so no more dropping) would help, but that may not be enough.
