I wonder if anyone had any experience with it yet?

I've worked with Greenplum for years, but I've been looking desperately for the open source alternative.

    Given how new it is, and how slow-moving the kinds of organisations that want column stores often are, you'll probably be in the forefront of people looking to apply it to real world uses. – Craig Ringer May 28 '14 at 6:36
