=item B |
51
|
|
|
|
|
|
|
|
52
|
|
|
|
|
|
|
Returns connected L object. |
53
|
|
|
|
|
|
|
All options for connect_pool are similar to the AnyEvent::MySQL->connect method. |
54
|
|
|
|
|
|
|
But pool accepts additional options in parameters hashref(4th parameter). |
55
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
AnyEvent::MySQL->connect_pool($dsn, $user, $password, {PoolSize => 5, CheckInterval => 10, Dispatcher => 0}, $callback); |
57
|
|
|
|
|
|
|
|
58
|
|
|
|
|
|
|
PoolSize => how many connections should be created. 5 connections by default. |
59
|
|
|
|
|
|
|
|
60
|
|
|
|
|
|
|
CheckInterval => Interval for ping connections. 10 seconds by default. |
61
|
|
|
|
|
|
|
|
62
|
|
|
|
|
|
|
Dispatcher => Determines return-value type. If true, connect_pool will return dispatcher object, instead of pool object. You can use dispatcher object |
63
|
|
|
|
|
|
|
as regular AnyEvent::MySQL connection object, pool will do it's own behind the scene. |
