@jroesch Yes, the behavior you mentioned is desired. That is designed by me to mimic the behavior of `logging.warning` in python's built-in library. The principle is that a warning message should be printed only once. However, this behavior does not affect performance. Because if you see such a warning, it means the returned config is a `None`. The 'None' will be cached in `FallbackContext`. Caching a None does not affect anything. If next time you have a tuned config, it has a higher priority to be selected than the `None` in `FallbackContext`. If next time you still do not have a tuned config, then returning a cached `None` is the same as returning an uncached `None` ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
