> Query with an ORDER BY clause on a flattened column fails:

> > select `name`, `type`, flatten(kvgen(`compliments`)) as `compliments` from `user` order by `name`, `type`, `compliments` limit 2;
> Error: SYSTEM ERROR: SchemaChangeException: Failure while trying to materialize incoming schema. Errors:
