Jingsong Lee closed FLINK-30945.
--------------------------------
Resolution: Fixed
https://github.com/apache/incubator-paimon/issues/745
> FTS does not support multiple writers into the same table and topic
> -------------------------------------------------------------------

> Key: FLINK-30945
> URL: https://issues.apache.org/jira/browse/FLINK-30945
> Project: Flink
> Issue Type: Bug
> Components: Table Store
> Reporter: Vicky Papavasileiou
> Priority: Major
>
> When creating two different streaming jobs that INSERT INTO the same table
> and kafka topic, the second job is never able to make progress as the
> transaction gets constantly aborted due to the producer getting fenced.
> FTS should set the transactionalIdPrefix to avoid transactions of different
> jobs clashing.
