Valentin Kulichenko commented on IGNITE-1403:
---------------------------------------------
Predicate, unlike cluster group can be invoked from Ignite internals where it's
not safe to do any kind of locking. Therefore it's not easy to make predicate
dynamic, mostly because {{ClusterGroupAdapter#nodes()}} method acquires gateway
lock. Since issue doesn't seem to be critical, I will close it now. It's always
possible to use {{ClusterGroupAdapter#predicate()}} method to get predicate
based on latest topology version.
> forOldest() cluster group returns predicate that is not updated when topology
> changes

> {{AgeClusterGroup}} that implements {{forOldest()}} and {{forYoungest}}
> cluster groups is dynamically updated when topology changes. But the
> predicate that can be acquired from this group via {{predicate()}} method is
> static, which is incorrect.
