Hello, The different than the more than 100 other NoSQL databases are: nessDB is very fast, on-disk storage engine,it's using LSM-Tree, which has a very better performance than B+Trees.There are a performance comparison test with tcbdb,MongoDB here:http://paste2.org/p/1844476 nessDB is a disk-storage engine, I think this is the main different with Redis DB.

Thanks, BohuTANG
