> I ran the below test against the private branch of Jason which has some patches for bugs related to flatten which are not yet merged into the master.
> When we run the flatten operator on a record which contains 100 maps in a repeated type, the output is only showing 41 records. However everything works fine when repeated type contains only 50 records.
> Below is the query that I used
> {code}
> select id, flatten(evnts) from `json_kvgenflatten/array-length-100.json`;
> ...
> ...
> 40 rows selected (0.2 seconds)
> {code}
> I attached the dataset. Let me know if you have any questions.
