Hey, nessDB is a very fast key-value,embedded Database Storage Engine (Using log-structured-merge (LSM) trees) with Level-LRU, Bloom-Filter,and supports Redis-Protocol(PING,SET,MSET,GET,MGET,DEL,EXISTS,INFO,SHUTDOWN).

This version, there is a big performance improving, using LSM-Tree. All the magic is in the codes, you can go through it here:https://github.com/shuttler/nessDB

1.8-rc1 key features: a) Better performances on Random-Read/Random-Write b) Log recovery c) Using LSM-Tree as storage engine d) Background detached-thread merging e) Level LRU f) Support billion data

How is this different than the more than 100 other NoSQL databases? If it supports the Redis protocol them why can I not choose toUse Redis? Or memcached? I am not trying to shoot this project down - I am just trying to understand all this " not invented here" syndrome.

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
