> I am not sure how nulls are supposed to be stored in text tables, but after loading some data with "null" or "NULL" strings, or x00 characters, we get bunch of annoying logging from LazyPrimitive that data is not in INT format and was converted to null, with data being "null" (string saying "null", I assume from the code).
> Either load should load them as nulls, or there should be some defined way to load nulls.
