Ian Boston created OAK-4943: ------------------------------- Summary: Keep Lucene Commits so that if the Segments file gets corrupted recovery can be attempted. Key: OAK-4943 URL: https://issues.apache.org/jira/browse/OAK-4943 Project: Jackrabbit Oak Issue Type: Improvement Components: lucene Affects Versions: 1.6 Reporter: Ian Boston
Currently, Lucene deletes all previous generations of the segments files as it has it uses the default IndexDeletionPolicy. Changing this to an IndexDeletionPolicy that keeps a number of previous segments files will allow an operator to find the most recent valid commit when the current segments file reports corruption. The patch found at https://github.com/apache/jackrabbit-oak/compare/trunk...ieb:KeepLuceneCommits keeps 10 previous commits. A more sophisticated policy could be used to save commits non-linearly over time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
