This article mainly introduces "how to use fastcgi mode to improve RGW concurrency". In daily operation, I believe many people have doubts about how to use fastcgi mode to improve RGW concurrency. Xiaobian consulted all kinds of data and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubt of "how to use fastcgi mode to improve RGW concurrency". Next, please follow the editor to study!

Take the main () of the rgw service as the entry, and view the initialization process of the entire fastcgi. The code is as follows

# src/rgw/rgw_main.ccint main (int argc, const char * * argv) if (framework = = "fastcgi" | | framework = = "fcgi") {RGWProcessEnv fcgi_pe = {store, & rest, olog, 0}; fe = new RGWFCGXFrontend (fcgi_pe, config); dout (0) rgw_thread_pool_size, conf); return 0;}}

The default rgw_thread_pool_size is 100. the code definition is as follows

# src/common/config_opts.hOPTION (rgw_thread_pool_size, OPT_INT, 100)

Find max_connections=num_threads + (num_threads > > 3) through the constructor of RGWFCGXProcess, that is, max_connections=100+1=101 by default, which is also mentioned in the code comments to ensure that as many requests are processed as possible.

# src/rgw/rgw_process.hclass RGWFCGXProcess: public RGWProcess {int max_connections;public: / * have a bit more connections than threads so that requests are * still accepted even if we're still processing older requests * / RGWFCGXProcess (CephContext* cct, RGWProcessEnv* pe, int num_threads, RGWFrontendConfig* _ conf): RGWProcess (cct, pe, num_threads, _ conf), max_connections (num_threads + (num_threads > > 3)) {} void run () Void handle_request (RGWRequest* req);}

So num_threads controls the number of max_connections, and if you want to increase the maximum number of concurrency of a single rgw process, you need to increase rgw_thread_pool_size.

At this point, the study on "how to use fastcgi mode to improve the number of RGW concurrency" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it! If you want to continue to learn more related knowledge, please continue to follow the website, the editor will continue to work hard to bring you more practical articles!
