--------------------------------------------
Thanks!
> Pass sender consistendId instead of ClusterNode to handler
> ----------------------------------------------------------

> Key: IGNITE-18319
> URL: https://issues.apache.org/jira/browse/IGNITE-18319
> Project: Ignite
> Issue Type: Bug
> Components: networking
> Reporter: Roman Puchkovskiy
> Assignee: Roman Puchkovskiy
> Priority: Major
> Labels: ignite-3, tech-debt
> Fix For: 3.0.0-beta2
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Currently, {{DefaultMessagingService#onMessage()}} throws an
> {{AssertionError}} if the message sender is not in the physical topology.
> As this is an expected behavior (a node can sometimes leave), it seems
> correct to handle this gracefully.
> The idea is to allow the handler resolve node by consistentId by itself and
> then decide what to do with a missing {{{}sender{}}}. Some of handlers don't
> even care about the sender because they do not send any response. There is
> also one handler that only cares about consistentId.
> A thing to reflect on: a node might disappear from a physical topology
> because of one of the two reaasons: either network connectivity is lost for
> some time, or a node stopped (maybe as a part of a restart). Do we need to
> account for this difference?
