I’ve noticed that when I created a reflection from a VDS that contains a window function (in my case, a RANK function), Dremio is unable to use this reflection in my queries, saying that the reflection “did not cover”. I’ve made the same test in the same VDS by removing the rank function, and the reflection worked like a charm.
Does anybody have any idea why it happens, and what I can do to solve this issue?
