介紹

Tarantool是一個NoSQL數據庫，運行在Lua編程語言中。 它利用了Node.JS強大的網絡編程功能，數據存儲利用了Redis持久化功能。

特性

• a drop-in replacement for Lua 5.1, based on LuaJIT 2.0; simply use #!/usr/bin/tarantool instead of #!/usr/bin/lua in your script,
• Lua packages for non-blocking I/O, fibers and HTTP,
• MsgPack data format and MsgPack based client-server protocol,
• two data engines: 100% in-memory with optional persistence and a 2-level disk-based B-tree, to use with large data sets,
• secondary key and index iterators support,
• asynchronous master-master replication,
• authentication and access control.

示例代碼：

#!/usr/bin/env tarantool

box.cfg{}
hosts = box.space.hosts
if not hosts then
    hosts = box.schema.create_space('hosts')
    hosts:create_index('primary', { parts = {1, 'STR'} })
end

local function handler(self)
    local host = self.req.peer.host
    local response = {
        host = host;
        counter = hosts:inc(host);
    }
    self:render({ json = response })
end

httpd = require('http.server')
server = httpd.new('127.0.0.1', 8080)
server:route({ path = '/' }, handler)
server:start()
