apache-kudu - Can I add more than 300 columns in Apache Kudu?

Question

I have been asked to create a Kudu table.

I know that Kudu is a columnar storage, but now my company's database table has like 285 columns which can fit in the the Kudu table, but is it possible to dynamically add columns in excess of the 300 column limit in a Kudu table? If so, how?

Answer 1

不知道如果超过 300 cols 限制会发生什么，但你在这里：--unlock-unsafe-flags --max-num-columns=1000

参考

Answer 2

@HJSG Kudu 的最佳性能是 < 300 列，Kudu 表最多可以有 300 列。这是 Kudu 限制。看看这个https://kudu.apache.org/docs/known_issues.html#_columns
