Review Comment:
> just for my understanding ar we thinking that the rowdata sent in on the
lookup would contain the pushdown predicates so the code could call and this
would handle the predicates and the keys:
> statement = lookupKeyRowConverter.toExternal(keyRow, statement);
> we could then remove the need for?
> statement = setPredicateParams(statement);
What I was proposing is showing the predicates in the digest of lookup join
node. That way, we can see it in the test xml files, and also it can be shown
in Flink Web UI.
