Josh Elser commented on CALCITE-645:
------------------------------------
bq. The data model is basically the same as JDBC returning a list of
SQLException objects, so the data passing over the Avatica protocol should look
similar.
Great. Thanks for that pointer. I've been a little mystified about what ODBC
actually looks like (aside from what I can see in Hive) :)
bq. Note that Bruno Dumon's patch to CALCITE-912 does some work on exception
handling.
Thanks, I hadn't paid close enough attention to the changes there. I'll take a
look.

> Avatica RPC response objects should contain an exception field that can be
> deserialized and re-thrown on the client side. That way client sees stack
> traces that are more meaningful than "500 error".
