  Go ahead and downvote this; but where's the source? Otherwise isn't this pointless bragging?

    It is not pointless for Uber. Please read it as a job advertisement for scalable database experts.

    So according to this post they created geographically distributed, multi master (with a mesh topology) that is always consistent. Either they created a holy grail of databases, or an opportunity to write a great Post-Mortem in the future.

      Or it's just incredibly slow and not always available

      It's a little unclear from the article, but based on > Since the system supports asynchronous replication, our data centers eventually become consistent. Writes are considered complete as soon as the remote data center acknowledges it. I assume its eventually consistent (so AP). I wish they compared why normal mysql async replication fails for them and they needed to build this though.
