Manfred Baedke updated OAK-4528: -------------------------------- Fix Version/s: 1.4.8 > diff calculation in DocumentNodeStore should try to re-use journal info on > diff cache miss > ------------------------------------------------------------------------------------------ > > Key: OAK-4528 > URL: https://issues.apache.org/jira/browse/OAK-4528 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: core, documentmk > Reporter: Vikas Saurabh > Assignee: Marcel Reutegger > Priority: Minor > Labels: observation, resilience > Fix For: 1.6, 1.5.6, 1.4.8 > > Attachments: queue-oak-4715.png, queue.png > > > Currently, diff information is filled into caches actively (local commits > pushed in local_diff, externally read changes pushed into memory_diff). At > the time of event processing though, the entries could have already been > evicted. > In that case, we fall back to computing diff by comparing 2 node-states which > becomes more and more expensive (and eventually fairly non-recoverable > leading to OAK-2683). > To improve the situation somewhat, we can probably try to consult journal > entries to read a smaller-superset of changed paths before falling down to > comparison. > /cc [~mreutegg], [~chetanm], [~egli] -- This message was sent by Atlassian JIRA (v6.3.4#6332)
