I saw you posted the same question to the Apache Kudu users mailing list. Here's the response I wrote there:
Check out this older post by Todd Lipcon about the 300 column limit: http://mail-archives.apache.org/mod_mbox/kudu-user/201706.mbox/%3CCADY20s7iT7%2BrVZNhagnNFUjk7-nNMxJK6%2BnHV%2B2SzpHXKFxvmw%40mail.gmail.com%3E There are probably other folks who run with over 300 columns in their schemas, but it's not something Kudu developers are actively testing. You're certainly welcome to try it, and I'm pleased that your 400 column schema is working well for you, but just be aware that you may run into unforeseen issues.
