Denis Magda reassigned IGNITE-9880: ----------------------------------- Assignee: Artem Budnikov (was: Denis Magda) > Document MVCC write conflict exceptions > --------------------------------------- > > Key: IGNITE-9880 > URL: https://issues.apache.org/jira/browse/IGNITE-9880 > Project: Ignite > Issue Type: Task > Components: documentation > Reporter: Vladimir Ozerov > Assignee: Artem Budnikov > Priority: Major > Fix For: 2.7 > > > When an entry is read (1) inside a transaction and then updated (2), there is > a chance that concurrent transaction will modify that entry in between (1) > and (2). In this case an error is thrown from the first transaction when > action (2) is performed and transaction is marked as "rollback only". User > need to re-try the whole transaction in this case. > When native APi is used, then {{CacheException}} is thrown with special > message {{Cannot serialize transaction due to write conflict (transaction is > marked for rollback)}}. This will be changed in future (AI 2.8|) - special > exception type will be thrown. > When JDBC or ODBC are used, then special SQLSTATE code 40001 (aka > "Serialization failure") is propagated to user. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
