[jira] [Commented] (OAK-3710) Continuous revision GC

    [ https://issues.apache.org/jira/browse/OAK-3710?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16091519#comment-16091519 ] 

Marcel Reutegger commented on OAK-3710:
---------------------------------------

Added an option to the DocumentNodeStoreService ({{versionGCContinuous}}) that enable continuous Revision GC (default: false). Implemented in trunk: http://svn.apache.org/r1802289

There are still some details to figure out. With the option enabled, the {{VersionGarbageCollector}} logs info messages every five seconds. Those messages are useful when GC runs e.g. every 24 hours, but are too verbose when run frequently.

> Implement continuous revision GC cleaning up documents older than a given threshold (e.g. one day). This issue is related to OAK-3070 where each GC run starts where the last one finished.
> This will avoid peak load on the system as we see it right now, when GC is triggered once a day.
