I'm guessing you've seen the nodejs driver docs here: https://github.com/datastax/nodejs-driver/tree/master/doc/getting-started is there something in particular you're looking for?

This one I saw. But there is no information about how to define a schema.

I can see only connection and query execution there

Ok so the driver should be compatible with normal CQL3 commands as per FAQ docs here says:

https://github.com/datastax/nodejs-driver/tree/master/doc/faq

>Which versions of CQL does the driver support?

>It supports CQL version 3.

So you should be able to use a normal create table statement. Note one word of caution when doing schema changes programmatically - dont throw those in like you would normal writes. They need to be done less frequently and with more care.
