[jira] [Comment Edited] (OAK-2793) Time limit for
HierarchicalInvalidator
[ https://issues.apache.org/jira/browse/OAK-2793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14509093#comment-14509093 ]

-------------------------------------------------------------
Attaching a [patch|^OAK-2793-Time-limit-for-HierarchicalInvalidator.patch] which would time out hierarchical cache invalidation. The patch reads a system property {{oak.mongo.cacheInvalidationTimeout}} (in ms). The default value is -1 which keeps timing out disabled.
I don't have a setup to have a comparison of changes in invalidation time taken or drop in performance. I'd update the issue once I get around to benchmarking those numbers.

> This issue is related to OAK-2646. Every now and then I see reports of background reads with a cache invalidation that takes a rather long time. Sometimes minutes. It would be good to give the HierarchicalInvalidator an upper limit for the time it may take to perform the invalidation. When the time is up, the implementation should simply invalidate the remaining documents.
