-- TODO: Tautological optimization breaks JIT expression compilation, because it can return constant result
|
|
-- for non constant columns. And then sample blocks from same ActionsDAGs can be mismatched.
|
|
-- This optimization cannot be performed on AST rewrite level, because we does not have information about types
|
|
-- and equals(tuple(NULL), tuple(NULL)) have same hash code, but should not be optimized.
|
|
-- Return this test after refactoring of InterpreterSelectQuery.
