Julian Reschke updated OAK-3189: -------------------------------- Component/s: rdbmk > CLONE - MissingLastRevSeeker non MongoDS may fail with OOM > ---------------------------------------------------------- > > Key: OAK-3189 > URL: https://issues.apache.org/jira/browse/OAK-3189 > Project: Jackrabbit Oak > Issue Type: Task > Components: core, rdbmk > Affects Versions: 1.0.18 > Reporter: Julian Reschke > Assignee: Julian Reschke > Fix For: 1.0.19 > > > (This clones OAK-2208 as that never made it into the 1.0 branch) > This code currently has a hardwired optimization for MongoDB (returning an > Iterable over a DBCursor). For all other persistences, a java List of all > matching NodeDocuments will be built. > I see two ways to address this: > 1) Generalize the Mongo approach, where a query to the persistence can return > a live iterator, or > 2) Stick with the public DS API, but leverage paging (get N nodes at once, > and then keep calling query() again with the right starting ID). > 2) sounds simpler, but is not transactional; [~mreutegg] would that be > sufficient? -- This message was sent by Atlassian JIRA (v6.3.4#6332)
