------------------------------------------
Summary: 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
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).
