Couchbase Server （前身是 Membase） 是一个分布式的面向文档的 NoSQL 数据库管理系统，该系统联合了 CouchDB 的简单和可靠以及 Memcached 的高性能。 网上有MongoDB与Couchbase的对比，请参考： http://www.infoworld.com/d/data-management/nosql-showdown-mongodb-vs-couchbase-214912 Couchbase主页： http://www.couchbase.com/ 本文的目标是搭建简单的Couchbase环境并用Java语言进行读写测试。 1.准备工作 1）下载 Couchbase Server ，本文用到的版本是 version 2.1.1 for win64 ，2.0在某些机器上装不上，内核问题。 2）下载 Java相关类库 相关下载链接： http://www.couchbase.com/download 2.安装Couchbase Server 1)安装过程很简单，在官网下载并安装即可。 2)安装完成后Couchbase Console程序会自动打开http://localhost:8091地址，这时候有可能会打不开，最有可能出现的问题就是端口被占用了。 （占用与否，可以用cmd查一下） 这时再打开http://localhost

I'm looking for one place that summarizes the main properties of the NoSQL databases that I keep seeing referenced - in particular, MongoDB, Riak, Redis, Memcached, Membase, and Cassandra. Types of queries, acid, architecture for/properties of scaling, etc. All in memory, overflow to disk, backup on disk, or mainly only indexes in memory? Probably one of the best source which summarizes basic information (and points you to more detailed source in the first place) about various nosql databases is this website. Other than that you should check out these: Cassandra vs MongoDB vs CouchDB vs Redis

It is fourth day already since I've started diving into CouchDB specifically Membase (Couchbase), Membase seems really interesting technology for me due to simplicity of administration, their interface is as magical as informal and simple. The way you add/remove buckets is just fun. Unfortunately I didn't managed to launch their .NET client on Mac OS X (on Windows it worked fine) and also couldn't find out the way to perform Map/Reduce queries so it seemed that Membase Server technology is little simpler then pure CouchDB. Anyway everything changed until recently I've stumbled upon the diagram

I have the Membase server installed with a couple buckets setup and I was looking for a good tutorial or example of how to use this as the 2nd level cache with NHibernate. I am interested in what a sample configuration would look like and if there is anything I need to do in code or if I can handle it all from my NHibernate mappings. Thanks for any assistance. In your mapping files, you will need to include the property: <class name="ClassName" table="Table"> <cache usage="read-write" /> <!-- SNIP --> </class> Options are read-write (read committed isolation), nonstrict-read-write (objects

I tried testing things on a VPS, and came close to 10K requests per second, and that was a simple 'hello world' servlet , let alone making a call to membase. My VPS was a 2 x Intel Xeon X5570, quad-core “Nehalem” architecture. Note: I'm not a java expert, nor a tomcat expert, this was on default settings. Does anyone else deal with such high traffic that could shed some light? I used apache bench, and I ran it maybe 4-5 times, doing about 100K requests to the server. original: how to handle 2000+ requests/sec on tomcat? Turn on NIO (Non-Blocking IO). This is not by default turned on. Without

What are the major differences between Redis and Membase? Scalability: Membase offers a distributed key/value store (just like Memcache), so writes and reads will always be performed in predictably constant time regardless of how large your data set is. Redis on the other hand offers just master-slave replication, which speeds up read but does not speed up writes. Data Redundancy It's simple to setup a cluster with a set amount of replicated copy for each key-value pair, allow for servers to failover a inoperative node in a cluster without losing data. Redis' master-slave replication doesn't
