I made almost no progress with nosql stuff and the worse thing is I don’t know why, it seems I cannot concentrate due to this or that kind of problems.
However, I do spend time on reading all sort of documents, though I cannot tell the exact reason, I’m going to focus on following projects:
- Cassandra, it impressed me on fail-over feature (built-in replica, auto bootstrap, etc)
- CouchDB, there are way too many people mentioned its name, though feature-wise I don’t think it’s enough (built-in replication, but not replica)
There are two second tier project I will take a look at them once I have time:
- MongoDB, it was said this is the one quite similar to CouchDB, but lack of some features
- MemcacheDB, it is more like a caching engine with persistent storage, but it could be one of the most reliable key/value pair DB
Cassandra is done by Java, while CouchDB is down by erlang, I’m not 100% familiar with either, pity :(.

Sorry, the comment form is closed at this time.
Alright, someone did a great comparison for me ๐

Obviously I made same conclusion as he did, at least Cassandra scored the highest.
People commented to the blog mentioning MongoDB becomes distributed now, I don’t think I have time testing though … but once I have time I will test MongoDB instead of CouchDB.
Again tough decision to choose where to go, I will settle done Cassandra first.
