Hey community,

I was following https://github.com/apache/iceberg/issues/9220 (Max number
of columns) and down the rabbit hole and I found there are a lot of
discussions about issues with tables having more than 1k columns.  However,
after reviewing discussions, it is still a little confusing to me. So I
would like to check here:

My questions are:
- Without considering performance penalty, do we have a hard limit on how
many columns an Iceberg table can have, and once we exceed that, we will
start to see failures?
- Is it reasonable to say we should still expect some other failures to
happen (but theoretically fixable) after a table has more than 1k columns?

I would appreciate your answer and I would love to help to document the
answer to my above questions.

Thanks!
