Riak Recap, November 19th 2016

Alexander Sicular-2

Hello Folks,

This is a fantastic beast of a recap with lots of great things to get to this weekend. We just announced Riak KV 2.2.0. This new version brings a host of goodies (with the requisite client libraries.) If you’re looking for something new to try out before next week with the in-laws, give it a try.

Are you working on something Riak related? Reply to me and I’ll get your talk, project or blog post in the next Riak Recap. Perhaps you’re interested in penning a guest post on the Basho blog? [0]
