Description

git.commit.id.abbrev=60aa446
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

select id, flatten(evnts) from `json_kvgenflatten/array-length-100.json`;
...
...
40 rows selected (0.2 seconds)

I attached the dataset. Let me know if you have any questions.
