Map of Golang Key Value Engines

Really great overview!

I've been tracking some of them for a while as part of evaluating which ones to add to my key-value abstraction library gokv [1], but others only noticed recently. It's really interesting that there's no single most popular implementation, but new ones emerging and gaining popularity regularly.

As I was confused on the many options of Go key value storage backends, I've created a map.

All feedback and ideas welcome.
