Wow. Probably fundraising and getting out front of googles new consumer spanner service. I just started experimenting w/ cockroachdb and it sounds/seems great. They def are campaigning hard, landing a Jepsen test and a lot of posts/articles last couple.
I am pulling for them over G on principle. I infer they know people at Stripe where the Rethink team & Aphyr are so hopefully they can learn from them and build an awesome product. G has lost a lot of battles on UX, Docs, attitude and just general product. They have won a lot of battles on sheer size & resources. Be nice to have this stick around.
