+## Configuration API {#configuration_api}
 
 To load the configuration, a dedicated thread first compiles the Lua code. It then calls the function `mcp_config_pools`, which loads all backends, collects them into pools, and returns a Lua table holding all of the final pool objects. Next, for each worker thread, they each execute `mcp_config_routes`. This function is expected to set up route handling (code that matches requests to a pool), and sets the command hooks that memcached will call (ie; hooks on get, set, and so on).
