		(NOT ONLY DATABASE ENGINE)
		Copyright (C) 2011 BohuTANG
================================================================	
  nessDB is written in ANSI C and works in most POSIX systems like Linux, *BSD, OS X and Solaris without external dependencies.
 
  Key Features
  =============
  * Bloom filter for record presence detection 
  * Level-LRU for hot data caching,improving Random-Read 
  * Distributable B+Tree-Structured-Indexes 
  * Background IO for data flush to disk
  * Redis protocol support

  Directory Tree
  ==================
  ./
  ./src/ 	- sources of nessDB
  ./BENCHMARK	- benchmark results of nessDB
  ./LEVEL-LRU	- nessDB's level-lru doc
  ./TODO	- nessDB's todo list
  ./x/		- nessDB's network layer(via redis),very high-performance.


  Interface
  ==========
    * db_init(int bufferpool_size,int isbgsync)
    * db_get(const char *key)
    * db_add(const char *key,const char *value)
    * db_update(const char *key,const char *value)
    * db_remove(const char *key)

    Very simple to use.

 
  How to do BENCHMARK
  ==================
	a, $cd src
	b, $make
	c, $./nessdb-bench add

	If you want to remove all indexes&datas,please use "$make cleanall"  command.

  Start as server
  ===============
  	* $./nessdb-server
	Now you can use redis-cli(or other redis's clients) to do some "COMMAND" operations
	(Support Redis-Style commands:PING,SET,MSET,GET,MGET,DEL,EXISTS,INFO).
	
 Thanks.
