> 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().
