Valentin Kulichenko commented on IGNITE-9365:
---------------------------------------------
Hi [~syssoftsol]. The change looks OK to me, although I'm not sure about the
way you handle null values. I don't think there should be anything special
about them - if both are nulls, then it's a match, otherwise it's not. Said
that, I think it's better to just get attribute values from both nodes and use
{{Objects.equals}} that already takes null values into account. That would
simplify the logic and make it more intuitive in my view. Do you agree?

> As a developer, I want to be able to force cache backups each to a different
> "Availability Zone", when I'm running out-of-the-box Ignite, without
> additional Jars installed. "Availability zone" is a AWS feature with
> different names for the same function by other cloud providers. A single
> availability zone has the characteristic that some or all of the EC2
> instances in that zone can fail together due to a single fault. You have no
> control over the hosts on which the EC2 instance VMs run on in AWS, except by
> controlling the availability zone .
>
> I could write a few lines of a custom affinityBackupFilter, and configure it
> a RendezvousAffinityFunction, but then I have to get it deployed on all nodes
> in the cluster, and peer class loading will not work to this. The code to
> do this should just be part of Ignite.
