Steven Hawkins commented on TEIID-3522:
---------------------------------------

There's a lot of complexity packed into the spec.  A first cut looks like it could be support for groupby, aggregate, and filter at both the top level and in a groupby.  But for now, I'll leave off the apply in expand.  I'll also leave off rollup support as we only have simplistic rollup support in the engine.
