[jira] [Commented] (SLING-9460) Avoid seeding messages in
PubQueueCache
[ https://issues.apache.org/jira/browse/SLING-9460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17112361#comment-17112361 ]
Timothee Maret commented on SLING-9460:
---------------------------------------
This is a great idea. The discovery messages are sent on a periodical basis with relatively short delay (10s on average per subscriber service).

> Key: SLING-9460
> URL: https://issues.apache.org/jira/browse/SLING-9460
> Project: Sling
> Issue Type: Improvement
> Components: Content Distribution
> Affects Versions: Content Distribution Journal Core 0.1.10
> Reporter: Christian Schneider
> Assignee: Christian Schneider
> Priority: Major
> Fix For: Content Distribution Journal Core 0.1.12
>

> We seed the cache to make sure we have a known minimal offset. So when a request for an older package comes in we can create an additional consumer that can then stop when it reaches the minimal offset.
> Instead of seeding we could wait until we receive the first discovery message. Then we can start from this offset.
