------------------------------------------
Summary: Add index storage format compatibility tests
Key: IGNITE-26109
URL: https://issues.apache.org/jira/browse/IGNITE-26109
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.
Here are the scenarios:
# Indexes remain built
## Index is fully built on v1
## On v2, the index must remain available and its nextRowId should remain null
(so it should not build again)
# Indexes proceed being built
## Index starts building, but the build is not finished
## Upgrade happens
## On v2, the build is continued and finishes successfully
