For those that are not familiar with Hyperdex[1], it is an open-source, performant, ACID compliant key-value store with commercial support[2] for fully distributed transactions.<p>It seems that Robert Escriva (creator of Hyperdex) is now working on a new database called Consus with the following key differences[3]:<p>“Consus has two (three) differences from HyperDex that I believe will make it more appealing in the long run:<p>1. Consus doesn't separate the implementations of transactions and the regular code. Once we have a paper public on the topic and I have clearance to release the code, all of the code will be available under the same license, with no commercial fork.<p>2. Consus provides wide-area, geo-replicated transactions with much lower latency than is possible in any other system I know with the same consistency that Consus provides.<p>3. I’m still actively working on Consus; I'm not actively working on HyperDex."<p>[1] <a href="http://hyperdex.org/" rel="nofollow">http://hyperdex.org/</a>

There's also a blog post announcement here: <a href="http://hack.systems/2016/12/13/hello-consus/" rel="nofollow">http://hack.systems/2016/12/13/hello-consus/</a><p>Reading through the post about active development on the predecessor HyperDex: <a href="https://github.com/rescrv/HyperDex/issues/233" rel="nofollow">https://github.com/rescrv/HyperDex/issues/233</a><p>> I've stopped developing the project for non-public reasons that aren't technically related to the project.<p>Along with this line in the blog post:<p>> not one in which a company with profit motives releases a half-open product, but one in which those interested in Consus can come together to build something better.<p>It seems like there was some friction around the commercial nature of Hyperdex.
Cool! Also, you might take a look at <a href="http://bedrockdb.com" rel="nofollow">http://bedrockdb.com</a> for a geo-replicated, ACID, SQL database (basically a replication layer atop SQLite).
