> Running the following query that contains kvgen() appears running out of
> memory and fails. There appears to be a 50 row limit. If I add a limit to the
> query, limit 50 or less works, with limit 51, the query fails.
> 0: jdbc:drill:schema=dfs.drillTestDir> select kvgen(sub.esr) from
> `es/esr-part` sub;
> The query returns result but fails in the middle of displaying the result. No
> other error message except the following stack:
