Vladimir Sitnikov commented on CALCITE-2535:
--------------------------------------------
[~zhztheplayer], while I agree there might be issues like "test should fail but
wrongly passed", and it is great you want to fix/improve that.
Juilan says that "exception handling" is tricky. And pease make sure that
Calcite engine does not over-optimize.
That is, there might be cases when "constant folder" would fold a computation
that would never be triggered during normal query execution(without constant
folder).
The rule #1 is "optimizer must not convert good SQL to a failing one".
> Runtime failure check not working in SqlTesterImpl.java
