Tokyo Cabinet (TC) 是日本第一大SNS网站mixi开发的,而Flare是日本第二大SNS网 站green.jp开发的。Flare简单的说就是给TC添加了scale功能。他替换掉了TT部分,自己另外给TC写了网络服务器,Flare的主要特 点就是支持scale能力,他在网络服务端之前添加了一个node server,来管理后端的多个服务器节点,因此可以动态添加数据库服务节点,删除服务器节点,也支持failover。如果你的使用场景必须要让TC可 以scale,那么可以考虑flare。
flare唯一的缺点就是他只支持memcached协议,因此当你使用flare的时候,就不能使用TC的table数据结构了,只能使用TC的key-value数据结构存储。
未正式发布1.0.13/14/15.上一个版本还是2011-03-01的1.0.12.可以做到持久化存储。

还不如直接memcached?!
