Josh Elser commented on CALCITE-840:
------------------------------------
bq. Could you do a union-like message as container for the different types that
end up in the untyped list? It's a shame that relatively expensive JSON parsing
is still needed presently.
Yes, I think that would work (assuming I understand you correctly: make an
"object" message that is one optional instance of every possible type). It
would be ugly to use (since I don't think we'd have a concise way to populate
that message without a big conditional block, and users would be forced to
unwrap it too), but it's a better solution than what I'm doing at the moment I
think :)
