Davide Giannella updated OAK-6412: ---------------------------------- Fix Version/s: 1.14.0 > Consider upgrading to newer Lucene versions > ------------------------------------------- > > Key: OAK-6412 > URL: https://issues.apache.org/jira/browse/OAK-6412 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: lucene > Reporter: Tommaso Teofili > Assignee: Tommaso Teofili > Priority: Major > Fix For: 1.12.0, 1.14.0 > > > An year ago I had started prototyping the upgrade to Lucene 5 [1], in the > meantime version 6 (and 7 soon) has come out. > I think it'd be very nice to upgrade Lucene version to the latest, this would > give us improvements in space consumption and runtime performance. > In case we want to upgrade to 6.0 or later we need to consider upgrade > scenarios because Lucene Codecs are backward compatible with the previous > major release, so Lucene 6 can read Lucene 5 but not Lucene 4.x (4.7 in our > case) therefore we would need to detect that when reading an index and > trigger reindexing using the new format. > Related to that there's also a patch to upgrade Solr index to version 5 (see > OAK-4318). > [1] : https://github.com/tteofili/jackrabbit-oak/tree/lucene5 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
