资 源 简 介
Most MySQL drivers (and database drivers in general) are synchronous, i.e. the execution of a script is blocked until having connected to the database or having obtained the result of a query. This is often unacceptable for highload services, since one probably wants the script do something useful while MySQL server is executing a long query. So perl-mysql-async is developed to make asynchronous requests to the server: a script submits a query, specifies a callback for the result and continues executing in the libevent loop; when the result of the query is completely read from the server, the specified callback is called with the result as a parameter.
New versions of MySQL 4.1 protocol and newer versions are supported.
