[jira] [Commented] (SLING-10112) Distribution Queue can not be reliably cleared due to race condition processing delete messages

["Timothee Maret (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SLING-10112?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17368001#comment-17368001 ] 

Timothee Maret commented on SLING-10112:
----------------------------------------

This approach has a flaw with cloud deployments that treat Sling instances as a cattle. In those deployments, each instances starts with a new slingId. Commands are sent to a specific subscriber agent identified by subSlingId and subAgentName. As a result, the command is not being picked up when the instance is replaced.

We should revert this change given that SLING-10528 avoids the condition that required this change.

> Replication queue can not be reliable cleared due to race condition with processing the 'delete' messages.
> If the first message is stuck during processing, the 'clear queue' signal might never have effect on the subscriber.
> A restart of the process does not help as the same situation might occur.
