Retry Design Pattern

Comment

This pattern states that you can retry a connection automatically which has failed earlier due to an exception. This is very handy in case of temporary issues with one of your services.

Lot of times a simple retry might fix the issue. The load balancer might point you to a different healthy server on the retry, and your call might be a success.

final var op = new Retry<>(
    new FindCustomer(
        "1235",
        new CustomerNotFoundException("not found"),
        new CustomerNotFoundException("still not found"),
        new CustomerNotFoundException("don't give up yet!")
    ),
    5,
    100,
    e -> CustomerNotFoundException.class.isAssignableFrom(e.getClass())
);
