Spanner truly is remarkable. I've always wondered why google hasn't opened it up!

  Google does open source when it benefits them. Giving everyone else Spanner doesn't benefit them.

    It wouldn't benefit anyone. Spanner is most likely tightly coupled with their internal services and infrastructure. If you want to know how spanner works, read the paper. If you want to use it yourself, you'll need to build it on top of your own infrastructure, just like Google did.

    Or more when it doesn't harm them. Google's open-sourced several projects (Protocol Buffers, Closure, Gumbo) that didn't directly benefit Google, but also don't harm them or give away highly-valuable IP either.

  The article mentions that Spanner has dependencies on several other Google projects. Assuming Google wants to open it up (more than publishing a paper), they would need to stub out all the dependencies first, which is a major effort.

    It would make more sense to host it as a cloud API, or perhaps use it as a backend for Datastore: https://developers.google.com/datastore/ https://developers.google.com/datastore/ however according to this page: http://googledevelopers.blogspot.com/2013/05/get-started-with-google-cloud-datastore.html http://googledevelopers.blogspot.com/2013/05/get-started-wit... it seems like it uses Megastore http://www.cidrdb.org/cidr2011/Papers/CIDR11_Paper32.pdf http://www.cidrdb.org/cidr2011/Papers/CIDR11_Paper32.pdf
