RIAK Roadmap Workshop

I don’t want to hijack the thread, thanks for posting the roadmap, I hope all other interested parties can do the same. It’s going to be a very valuable meet up and I look forward to attending.

However, I’m sorry for being a picky picky pedant but I worked with the guy who built the HLL feature, and it is a thorough, diligent, and professional feature added as part of the release cycle. I was concerned about the GPL dependancy (Proper) but after some investigation it looks like it is OK since it is not shipped with Riak or linked in anyway, instead it is a test only dependancy brought in by the dependancy on Hyper (but we should still get more clarification there.) But the HLL work itself is top drawer, thoroughly tested, and reviewed (perhaps more so than many Riak features.)

I do think that in the develop and unreleased branches there is probably questionable code that isn’t yet production ready, but I need to defend the HLL work. It's good work. It’s my fault that you’ve got the wrong end of the stick about the HLL work because of my concerns over the GPL dependancy. Sorry.

We see the project going forward as a simple repo into which likeminded developers agree and contribute changes. Placing overbearing procedure and structure on what is currently a small community will dissuade other from joining and contributing.
