> We need to throw an exception when user attempts to create or alter a table 
> with a field declared as NOT NULL in a case the corresponding cache 
> configuration employs read-through cache store 
> {{CacheConfiguration.setReadThrough()}}.
> These features seem to not fit together quite well, so we skip the support at 
> the moment and the check will keep things consistent.
