There was a problem hiding this comment. I think there is no need to refactor the There was a problem hiding this comment. Maybe there is another way, but adding this to extra properties actually causes the tests to break since it is an unused property there. This sets it as a configuration property, but it needs to be a session property. The session is actually passed to the distributed query runner builder in it's constructor, so we need some way to add properties to that session before building the runner. This is why I decided to make changes to There was a problem hiding this comment. Ooh, sorry for the overlooking that |

There was a problem hiding this comment. Wondering if we need a whole separate test for this. Can't we just create a dataProvider which passes in true/false values and lets us construct a valid session in the beginning of the test method? Then you can pass the session to all of the execute/assertQuery methods? There was a problem hiding this comment. Can you elaborate on this please? I'm not sure what you are referring to as the separate test. I can have the data provider pass in one true and one false value and add a condition inside the test function itself, is that what you are asking for here? If so what purpose would that serve? Thanks |

I think we also need the mapping for the table below (prestodb -> iceberg)?

Actually I'm not sure about this. The below table contains...
I suppose with and without zone just represent
isAdjustedUTCin this case? Either way it looks like this part is covered. Maybe we should standardize the way we discuss these in the documentation though
