------------------------------------------
Summary: Add Metastore Raft log compatibility test
Key: IGNITE-26100
URL: https://issues.apache.org/jira/browse/IGNITE-26100
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 storage is flushed and the
node is stopped, its binary is replaced with v2, the node is started.
We must test the following scenarios:
# Reapplication of a log (written in v1) on v2 goes correctly. We could do the
following:
## Make sure the v1 log is complete (no prefix truncation happens)
## Delete partition files while the node is offline
## Start on v2 and make sure the table data becomes available after node
recovery
# Application of a log (written on v1) by a leader on v2 to another node (a
follower) also on v2 goes correctly: that is, after it finishes, on the
follower it is possible to read table data. We might need the following to test
this:
## Make sure the v1 log is complete (no prefix truncation happens)
## Originally, while on v1, have just 1 node in the cluster, so the
replication factor is 1
## After we start on v2, join two more nodes (on v2)
## Change replication factor to 3
## Wait for replication to finish
## Stop the original node
## Now query the table (as its partitions will still have majorities)
