[jira] [Commented] (KAFKA-9453) Make transaction.id optional in group mode EOS

    [ https://issues.apache.org/jira/browse/KAFKA-9453?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17064999#comment-17064999 ] 

Matthias J. Sax commented on KAFKA-9453:
----------------------------------------

[~bchen225242] Not sure if I understand this ticket. The `transactional.id` is not specified by the user but it's always generated by Kafka Streams. Can you elaborate?

> After 447, one of the big improvement is that we are no longer requiring single writer scope guarantee, so that user doesn't have to configure a unique transactional.id for transaction safety.
> In fact, without security concern, we could even avoid using initTransaction API as well.
