-----------------------------------------
Assignee: Filipp Shergalis
> Add Metastore snapshot file compatibility test
> ----------------------------------------------
>
> Key: IGNITE-26099
> URL: https://issues.apache.org/jira/browse/IGNITE-26099
> Project: Ignite
> Issue Type: Improvement
> Reporter: Roman Puchkovskiy
> Assignee: Filipp Shergalis
> 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 Metastore 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 Metastore group gets truncated and join a
> new node (in v2). This will cause Metastore storage replication using a
> snapshot file.
> After that, second node should function correctly (we could trigger a
> rebalance to make sure).
