> The below query results in 200006 records. Based on the data set we should only receive
200000 records. 
> {code}
> select s.uid from (select d.uid, flatten(d.map.rm) rms from `data.json` d) s order by
s.rms.rptd[1].d;
> {code}
> When I removed the order by part, drill correctly reported 200000 records.
> {code}
> select s.uid from (select d.uid, flatten(d.map.rm) rms from `data.json` d) s;
> {code}
> I attached the data set with 2 records. I copied over the data set 50000 times and ran
the queries on top of it. Let me know if you have any other questions
