This allows you to plug the behavior that the LLRC uses to handle warnings on a per request basis. We entertained the idea of allowing you to set the warnings behavior to strict mode on a per request basis but that wouldn't allow the high level rest client to fail when it sees an unexpected warning. We also entertained the idea of adding a list of "required warnings" to the `RequestOptions` but that won't work well with failures that occur *sometimes* like those we see in mixed clusters. Adding a list of "allowed warnings" to the `RequestOptions` would work for mixed clusters but it'd leave many of the assertions in our tests weaker than we'd like. This behavior plugging implementation allows us to make a "required warnings" option when we need it and an "allowed warnings" behavior when we need it. I don't think this behavior is going to be commonly used by used outside of the Elasticsearch build, but I expect they'll be a few commendably paranoid folks who could use this behavior. |
