----------------------------------------
Assignee: Aditya Mukhopadhyay
> Add CMG snapshot file compatibility test
> ----------------------------------------
>
> Key: IGNITE-26104
> URL: https://issues.apache.org/jira/browse/IGNITE-26104
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Assignee: Aditya Mukhopadhyay
> Priority: Major
> Labels: ignite-3
>
> Legend: v1 is original version (3.0), v2 is current version (version from
> main branch).
> It is supposed that data is written in v1, then the CMG storage is flushed
> and the node is stopped, its binary is replaced with v2, the node is started.
> Then we make sure the Raft log of CMG group gets truncated and join a new
> node (in v2). This will cause CMG storage replication using a snapshot file.
> After that, second node should function correctly (it should see logical
> topology changes).
>
> upd: similar to https://issues.apache.org/jira/browse/IGNITE-26099,
> TruncateSuffix job should be reused after it merged
