Here is the list I composed during the weekend:
- Redis – No big name (yet?)
- MemcacheDB – Used by sina.com.cn
- MongoDB – SourceForge
- Tokyo Cabinet and Tokyo Tyrant – Used by mixi.jp
- Cassandra – Used by Facebook and Digg
- Voldemort – Used by linkedin
- Riak – No known web sites yet.
- CouchDB – Used by BBC and Ubuntu (the Ubuntu One project)
- Dynomite – A clone of Amazon’s Dynamo, seems no user yet.
I’m not sure if I should try out these projects, the major concern is that I don’t have confidence on grid (hadoop, etc) about their latency:
and I won’t consider these because they are relying on specific providers:
- BigTable
- Dynamo
- [Could be more …]
Java and erlang are pretty popular here – I don’t like one of them, and I don’t know much about the other, tough.
