Project Voldemort. Yet Another “big, distributed, persistent, fault-tolerant hash table”—this time from LinkedIn, released under the Apache 2.0 license. The approach to consistency is interesting—instead of using distributed transactions, they use versioning and “resolve inconsistencies at read time”. It also uses consistent hashing (as seen in libketama) to select servers. The design document has lots more information.

Where did you see that it was from LinkedIn? I was looking on the website before and it had no references to who created it. Looks like a pretty great project though.

It says so about half way down the homepage - try searching for "linkedin".
I think that's the way CouchDB handles consistency too (versioning).
