Work Description: kanterov commented on issue #9119: [BEAM-6783] byte[]
breaks in BeamSQL codegen
URL: https://github.com/apache/beam/pull/9119#issuecomment-514365684
@amaliujia good point, I was looking into Calcite code and didn't find a
definite answer. In my understanding, Strict documentation should say "returns
null iff (if and only if) at least one argument is null", meaning that UDF will
never accept or return null, and wrapping implementor will handle that.
