[I] Feature request: Add retry with predicate [pekko]
He-Pin opened a new issue, #1268:
URL: https://github.com/apache/pekko/issues/1268
The current retry in pekko will trigger the retry when the future completes with an exception, but at $work, we may not want to retry for some exception/ value.
I'm using something like :
```java
@SneakyThrows
public static <V> V retryWithBackoff(
final Callable<V> callable,
final Predicate<V> shouldRetryPredicate,
final int maxRetryTime,
final int sleepInMills,
final String hint) {
return retryWithBackoff0(callable, shouldRetryPredicate, maxRetryTime, 0, sleepInMills, hint);
}
```
usage:
```java
result = RetryUtil.retryWithBackoff(
() -> bindTopic0(namespace, tagTopic, subscriber, subscriptionOptions),
r -> r != null
&& ErrorConstants.ERR_HSF_CALL_ERROR.equals(r.getErrorCode())
&& SwitchConfig.ENABLE_BIND_RETRY,
1,
5,
"bindTopic0");
```
at work, but I think we can adjust that for Pekko too.
where the `shouldRetryPredicate` can be a `(value,throwable) => Boolean`.
