Haven't you noticed the pedigree obsession of some in our field?

In this context it adds more signal than noise. There are zillions of open source projects but when you need to use them in production a very small subset of this universe is ready.

Does it? I don't think ex-Googlers gives anything of value here.

Are there distributed data stores like this that are also resilient to intentional sabotage? I've been looking recently at long-term digital preservation systems -- tools designed to archive large amounts of data for decades. This is the Library of Alexandria problem -- how do we preserve all this data we're generating against once-in-a-century disasters? So this 2005 paper lists thirteen different threats to long-te…

Journaling or storing incremental backups (perhaps offline?) of validated/verified checkpoints may address this, although it sounds like something you wouldn't be happy with since it's not a 'built-in' feature but an additional backup & maintenance process that a system administrator would need to implement.

I guess you're asking whether there exists a distributed fault-tolerant with a form of version control (similar to git/cvs/perforce) as part of the native feature set.

So I cannot tell if this is aiming to be CA or AP. Having beaten my head against the CAP wall for a while, how does it deal with partitions?

First off, you can't have CA in a distributed system, but I'm guessing that was a typo and you meant CP or AP. Given that it is based on spanner, and claims to have something close to linearizability, it is CP.

> are there distributed data stores that can be configured to resist intentional destruction of data?

Well, Git has checksums on everything.

It indicates that the project is worth a closer look rather than waiting or dismissing it outright.
