-------------------------------
Summary: The old transaction is not interrupted when Epoch renew
retry
Key: KYLIN-5308
URL: https://issues.apache.org/jira/browse/KYLIN-5308
Project: Kylin
Issue Type: Bug
Reporter: Jiale He
Attachments: image-2022-11-28-16-32-00-356.png
kylin fails to write data to the new transaction because the old transaction is
not interrupted during the Renew Epoch Retry. As a result, Kylin loses the
epoch.
When Epoch Renew occurs, the write to the database times out and tries again.
As the old transaction is not rolled back during the retry, the old transaction
is successfully written to the database and MVCC+1 occurs. When a new
transaction writes to the database, it will check the MVCC. If the detection
fails, kylin will think that the Epoch is lost.
