Oracle 12c in-memory option I've been told that there's an oracle in-memory option for 12c and that it uses columnar compression to get some great query speeds. I'd like to leverage it for some business intelligence stuff. I've been searching google and the only thing I can find are announcements and news articles. Does anyone have any code snippets or any directions on where I should look to implement this or learn more about it?
It's still in beta.  It won't be released till the 12.1.0.2 patchset.  As such, unless you're in the beta program, not much information is available yet.

I think the NDA has been lifted, as I saw Tom Kyte speak about it at Collaborate 14 in Las Vegas a couple of weeks ago, but, you can't actually use it yet.

Hope that helps.
