> Reporter: Wellington Chevreuil

> We have some customers use case finding useful to have some of the
> BucketCache configurations dynamically set, such as the accept factor or the
> queue addition wait time.
> HBASE-28517 has already made some other cache related properties dynamically
> configurable, and CacheConfig already implements the
> ConfigurationObserver and registers itself for config changes notifications.
> Since CacheConfig holds a reference for the BlockCache implementation, we
> could just allow for BlockCache implementation to define their own dynamic
> configuration logic by define a refreshConfig method in the BlockCache
> interface that would get called from CacheConfig.onConfigurationChange().
