Davide Giannella updated OAK-3494: ---------------------------------- Fix Version/s: 1.4 > MemoryDiffCache should also check parent paths before falling to Loader (or > returning null) > ------------------------------------------------------------------------------------------- > > Key: OAK-3494 > URL: https://issues.apache.org/jira/browse/OAK-3494 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: core, mongomk > Reporter: Vikas Saurabh > Assignee: Marcel Reutegger > Labels: performance > Fix For: 1.4, 1.3.10, 1.2.9, 1.0.25 > > Attachments: OAK-3494-1.patch, OAK-3494-2.patch, > OAK-3494-TestCase.patch, OAK-3494.patch > > > Each entry in {{MemoryDiffCache}} is keyed with {{(path, fromRev, toRev)}} > for the list of modified children at {{path}}. A diff calcualted by > {{DocumentNodeStore.diffImpl}} at '/' (passively via loader) or > {{JournalEntry.applyTo}} (actively) fill each path for which there are > modified children (including the hierarchy) > But, if an observer calls {{compareWithBaseState}} on a unmodified sub-tree, > the observer will still go down to {{diffImpl}} although cached parent entry > can be used to answer the query. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
