What would be the difference between this and an SSD-based keystore and an instance of memcached with as much RAM as was necessary to hold the whole dataset?

It appears to pool RAM from many servers. That would allow pool sizes larger than what fits in a single physical server.

Does this mean Atlassian products will be quick(er)? Perhaps they should concentrate there if not.

It's not by Atlassian...

Sure, but the URL is for Atlassian.net

similarly, you can have a memcached cluster

They just host the site, it is their wiki product called Confluence. The same way Github hosts pages at github.io but has nothing to do with content that people host there.

Is this still maintained? It's a really cool project, it's just so insanely fast. I once implemented a MariaDB storage engine that used RAMCloud for storage, and it was an eye-opening experience. With blazingly fast reads and writes, latency was the number one performance issue for us.

Did you use it in production ?

> Durability: RAMCloud replicates all data on nonvolatile secondary storage such as disk or flash, so no data is lost if servers crash or the power fails.

How does this work if someone is doing multiple sequential writes? Doesn't backup-ing to disk take a lot longer than writing to _RAM_ meaning some writes could get lost?

No it was part of a semester project at university.
