Yugabyte is a cloud-aware "planet-scale" database with a Postgres binary-compatible protocol layer.
Based on my database experience over many years with many, many databases, I have a good opinion about Yugabyte and about their claims.
In the past, Yugabyte did not work with Relstorage but with the most decent version of Yugabyte and Relstorage I have good feeling that Plone could benefit a lot from Yugabyte when it comes to scalable solutions.
For the first time I am able to run Zope (ZMI and basic ZMI operations) against Yugabyte. So it seems that the combination Zope/Plone + Yugabyte through Relstorage and Psycopg2 seems to work.
However creating a Plone site fails at commit time (obviously to some connection timeout):

Anyone with Relstorage know-now having some idea
