> Running the while ITCase takes ~3 minutes on my machine, which is not acceptable for developer productivity and is also quite the burden on our CI systems and PR iteration time.
> The issue is mostly that this does many costly operations, such as compiling SQL queries. Some tests are inefficient in that they do a lot more repetitions or test things that are not needed here. Also {{LocalExecutor}} itself is a bit wasteful because every time a session property is changed, when opening a session, and for other things we trigger reloading/re-parsing the environment, which means all the defined catalogs, sources/sinks, and views.
