Connection Pooling

Hello. The question is easy: Has Yii any connection pooling system in order to get open db connections to support big amount of simultaneous connections?

Thanks.

Yii is written in PHP using PDO abstraction layer. You can use any connection pooling available for PHP (PHP persistent connections, pgpool, etc). And because PHP is request oriented (every request is handled independently) you cannot "pool" resources any other way than that provided by PHP itself…
