Subject Re: UNNEST function
Date Tue, 08 Jan 2019 20:18:25 GMT
The support for UNNEST was in the calcite branch and took advantage of the
compilation support there. We unfortunately don't have the same support in
the mainline branch. We'd welcome a contribution in this area, but it'd be
a fair amount of work.
Thanks,
James
