Examples of Ngx_lua use techniques and applications in production environments

Lua's performance is Super Bull, and this doesn't have to be verbose.

The application scene of Nginx_lua

Network I/O blocking time is much higher than CPU computing time, while upstream resource non bottleneck (scalable) network applications, such as High-performance network middle tier, HTTP REST interface services, etc.

Expect to simplify the system architecture, let the service to the Nginx of the Web site;

Taobao people for NG next page X_lua use summary:

Advantage:

Synchronous non-blocking I/O forms intuitive and easy to understand, concurrent service capability is strong

Low CPU and memory running cost

High bonding with nginx can facilitate the adhesion of existing Nginx module functions

Disadvantage:

New technology solution, Lua compared to PHP, Ruby and other widely used development

Language, peripheral ancillary facilities are not yet sound enough to require time to accumulate

Installation is simple once again, in fact, we use openresty on the line. The author has done a lot of tuning.

It is recommended that you use Openresty. At least in the test environment with this, you can save a lot of search module, toss the module time.
