   Great question. I believe we might not handle min/max value properly in segment metadata in certain corner cases, and I'm sure there are some historic segments that do not have the min/max value set properly. We should make the check more strict (e.g. check if min/max value exist) to ensure the segment metadata can be used to solve the query.
