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.
