This project provides declarative retry support for Symfony applications.
Installation
Annotation example
use Symfony\Bundle\Retry\Annotations\Retryable;
use Symfony\Bundle\Retry\Annotations\Backoff;
class AppService {
/**
* @Retryable(
* retryFor="\LogicException",
* noRetryFor="\InvalidArgumentException",
* maxAttempts=5,
* delay=100,
* multiplier=2
* )
*/
public function retryableMethod($arguments) {
}
}Arguments
retryFor
Exception types that are retryable. Defaults to empty (and, if noRetryFor is also empty, all \Throwable are retried)
noRetryFor
Exception types that are not retryable. Defaults to empty (and, if retryFor is also empty, all exceptions are retried).
maxAttempts
The maximum number of attempts (including the first failure), defaults to 3.
backoff
Specify the backoff properties for retrying this operation.
delay
Delay in milliseconds between retries.
multiplier
Positive integer used as a multiplier to generate the next delay value.
@Backoff(delay=100, multiplier=2) with maxAttempts=4 will execute as following assuming that retryableMethod 3 times:
-> call retryableMethod (1st attempt)
-> wait 100 ms (initial delay value)
-> call retryableMethod (2nd attempt)
-> wait 200 ms (100x2)
-> call retryableMethod (3rd attempt)
-> wait 400 ms (200x2)
-> call retryableMethod (4th attempt)
-> return value to original caller or throw the caught exception
