Execution Scoped RetryPolicy

[ryanjbaxter]

I have come across a use case where I need to create a different RetryPolicy for each RetryTemplate.execute call. In my use case I am making an HTTP call that I want to retry but the RetryPolicy for that execution is based on information from the HTTP request being made. Given that we could be making multiple HTTP requests at the same time using a simple RetryTemplate is out of question because in theory we could be switching the RetryPolicy before a single request gets a chance to finish. I am wondering if others might think it would be useful to support a RetryPolicy for a given execution in addition to a global RetryPolicy for the template itself?
