[jira] [Commented] (OAK-5740) deliver overflow change even without new commit

["Vikas Saurabh (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OAK-5740?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15875975#comment-15875975 ] 

Vikas Saurabh commented on OAK-5740:
------------------------------------

The test case looks ok to me to show the point of the issue. That said, I'm still of the opinion that if this is observed only special case (e.g. controlled test case), then may be some util class/method (exposed?? in case some external observer want it!) would be ok. Of course, with the documented behavior.

bq. the observation queue is configured to be very large
I think the actual reason is that there are always commits that happen - update of ":async" node for example... may be even topology (although I don't know if that's true even in single-node-tar-setups too).

> As [reported|http://markmail.org/message/2qxle24f6zu2vpms] by [~catholicon] on oak-dev the observation queue only delivers the so-called _overflow entry/change_ only when new commits are 'coming in'. We might want to consider fixing this, even though arguably this is a very rare case (since typically the observation queue is configured to be very large)
