How to enable per-column compression when create table from impala?

>From the documentation

http://getkudu.io/docs/schema_design.html#compression

So how can I specify one column to be compressed when creating the table?

I've looked through the documentation but could not figure out the exact
SQL syntax.

Any hints?

JD or anyone, do you have a concise code example we can document? And a use case?

Hi Darren,

It's currently not supported in Impala, but you can do it via the Java or
C++ clients.
