In my opinion somewhere (on a higher level maybe)

I would very strongly recommend keeping the behavior consistent with
that of analytic DBMSes. I don't think that most analytic DBMS error
on overflows because it's too computationally expensive to check.
NumPy doesn't error (by default at least)

What do open source analytic database systems do? I don't think we
should deviate from the behavior of these systems. For example, you
can see that Apache Impala uses unsigned arithmetic on signed integers
Hi Palak,
The ParquetWriter class is meant to write a single parquet file (so in that
sense, that you see only a single parquet file being written based on the
shown code, that is expected).
If you want to write multiple files, you can either manually create
multiple ParquetWriter instances
https://github.com/apache/arrow/pull/7341#issuecomment-638241193
How should arithmetic kernels handle integer overflow?
The approach currently taken in the linked PR is to promote such that
overflow will not occur, for example `(int8, int8)->int16` and `(uint16,
uint16)->uint32`.
I'm not sure
Sounds good to me.
Regards
Antoine.
