[jira] [Updated] (OAK-9350) Index update: release the correct
checkpoint
[ https://issues.apache.org/jira/browse/OAK-9350?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas Mueller updated OAK-9350:
--------------------------------
Fix Version/s: 1.40.0
> Index update: release the correct checkpoint
> --------------------------------------------
>
> Key: OAK-9350
> URL: https://issues.apache.org/jira/browse/OAK-9350
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: indexing
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Priority: Major
> Labels: index
> Fix For: 1.40.0
>
>
> The async index update uses checkpoints to ensure consistency: it
> * 1. creates checkpoint2
> * 2. indexes everything between checkpoint1 and checkpoint2
> * 3. update the indexing lane to checkpoint2
> If there is s a problem before step 3, the checkpoint2 is removed. That's fine.
> However, if there is a problem after step 3 is complete, in some cases it also removes checkpoint2. This is incorrect, as checkpoint2 is needed.
> We have seen this is the case if the node store is closed, but dispose works. See OAK-9300. So fixing that should resolve most issues. However, the current code is still not correct.
