Yii Mutex Library - PostgreSQL PDO Driver
This library provides a PostgreSQL mutex implementation for yiisoft/mutex.
Requirements
- PHP 7.4 or higher.
PDO
PHP extension.
Installation
The package could be installed with Composer:
General usage
The package provides two classes implementing MutexInterface
and MutexFactoryInterface
from the yiisoft/mutex package:
There are multiple ways you can use the package. You can execute a callback in a synchronized mode i.e. only a single instance of the callback is executed at the same time:
Another way is to manually open and close mutex:
It could be done on lower level:
And if you want even more control, you can acquire mutex manually:
The PgsqlMutex
supports the "wait for a lock for a certain time" functionality. Using the withRetryDelay()
method, you can override the number of milliseconds between each try until specified timeout times out:
By default, it is 50 milliseconds - it means that we may try to acquire lock up to 20 times per second.
