> When you run a query with RANK, and one particular frame is too long to fit in 2 batches
of data, you will get wrong result.
> I was able to reproduce the issue in a unit test, thanks to the fact that we can control
the size of the batches processed by the window operator. I will post a fix soon along with
the unit test
