> Currently CachingKeyValueStore methods are synchronized at method level.
> It seems we can use read lock for getter and write lock for put / delete
> methods.
> For getInternal(), if the underlying thread is streamThread, the
> getInternal() may trigger eviction. This can be handled by obtaining write
> lock at the beginning of the method for streamThread.
