> Currently on joining a topology only affinity class name and partition number are checked between configurations of local and remote nodes.
> This is not enough in case of configured backup filter and possible extension with primary filter and can lead to disastrous situations due to node misconfiguration.
> We should implement something like {{AffinityValidator}} having signature as follows:
> {noformat}
> boolean validate(Affinity affinity)
> {noformat}
> Maybe it'll be useful for other grid objects as well, like {{CacheStore}},{{NodeFilter}}, etc.
