24/39 Ref: https://docs.oracle.com/cd/B28359_01/appdev.111/b28395/oci09adv.htm#LNOCI87728 Connection pool ➊ Reduces the number of times new connection objects are created. ➋ Promotes connection object reuse. ➌ Quickens the process of getting a connection. ➍ Minimizes the number of stale connections.

29/39 Async

30/39 Ref: https://wiki.swoole.com/wiki/page/517.html Async MySQL Client $db = new swoole_mysql; $server = array( 'host' => '192.168.1.1', 'port' => 3306, 'user' => 'test', 'password' => 'test', 'database' => 'test', 'charset' => 'utf8', ); $db->connect($server, function ($db, $r) { if ($r === false) { var_dump($db->connect_errno, $db->connect_error); die; } $db->query('show tables', function(swoole_mysql $db, $r) { if ($r === false) { var_dump($db->error, $db->errno); } elseif ($r === true ) { var_dump($db->affected_rows, $db->insert_id); } var_dump($r); $db->close(); }); });

35/39 Coroutine

36/39 Ref: https://wiki.swoole.com/wiki/page/604.html Coroutine: HTTP Client $httpclient = new Swoole\Coroutine\Http\Client('127.0.0.1', 80); $httpclient->setHeaders(['Host' => "api.mp.qq.com"]); $httpclient->set([ 'timeout' => 1]); $httpclient->setDefer(); $httpclient->get('/'); // to do something $http_res = $httpclient->recv();

37/39 Why not Go(lang)

38/39 Why not Go(lang) ➊ Not most developers in company are familiar with Go(lang). ➋ Not so many Go(lang) developers in Taiwan (future?). ➌ Training time. ➍ Swoole performance is close to Go(lang) in some cases.
