[jira] [Commented] (HIVE-24881) Abort old open replication txns

    [ https://issues.apache.org/jira/browse/HIVE-24881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17301364#comment-17301364 ] 

Anishek Agarwal commented on HIVE-24881:
----------------------------------------

[~klcopp] are you talking about replication txns on target ? 

These txns will be mapped by replication system, since replication happens based on event streams, we can partially abort these txns since we will not know where in the event stream we have to go back to replay as well as it will break the linear sequence of events.

Can you please elaborate a bit more on the use case affected or what are we trying to achieve ?
