             Summary: [SQL] Transactional consistency issues over JDBC
                 Key: IGNITE-27609
                 URL: https://issues.apache.org/jira/browse/IGNITE-27609
             Project: Ignite
          Issue Type: Bug
          Components: sql ai3
    Affects Versions: 3.2
            Reporter: Andrey Khitrin


Since 2026-01-15, our automated tests have started to periodically find consistency issues with transactional access over JDBC. I'm currently working on a simple reproducer, but the general approach for reproduction is the following:
 # Use JDBC (I'm not sure if thin client is affected or not);
 # Use transactions;
 # Read/update the same table from several threads;
 # Check consistency of updated table after some time.

Currently, there are at least two complex tests that periodically (~10% of time) fail on newer (after Jan 15) AI3 builds. Therefore, I consider that some breaking change may have had place slightly before that (somewhere around Jan 13-14, maybe). More information will be added.
