Regarding this example: https://resilience4j.readme.io/docs/examples-5
RetryConfig config = RetryConfig.custom()
.maxAttempts(2)
.waitDuration(Duration.ofMillis(100))
.retryOnResult(response -> response.getStatus() == 500)
.retryOnException(e -> e instanceof WebServiceException)
.retryExceptions(IOException.class, TimeoutException.class)
.ignoreExceptions(BusinessException.class, OtherBusinessException.class)
.build();
what exactly does waitDuration accomplish? Does it mean to timeout and retry after 100 ms? Or does it mean how long to wait before next retry?
