Ian Boston commented on OAK-3547: --------------------------------- With the latest commit to the branch, segments.gen is now stored in segments.gen_<epoch> and is immutable making it possible to correctly open previous generations. I think the patch is complete, unless a more sophisticated recovery mechanism is required. (ie flagging the index as requiring a rebuild, without actually doing it). Obviously needs extensive testing to see what happens when real repo corruption happens in a live cluster. At present only tested with a single instance on MongoMK. > Improve ability of the OakDirectory to recover from unexpected file errors > -------------------------------------------------------------------------- > > Key: OAK-3547 > URL: https://issues.apache.org/jira/browse/OAK-3547 > Project: Jackrabbit Oak > Issue Type: Improvement > Components: lucene > Affects Versions: 1.4 > Reporter: Ian Boston > > Currently if the OakDirectory finds that a file is missing or in some way > damaged, and exception is thrown which impacts all queries using that index, > at times making the index unavailable. This improvement aims to make the > OakDirectory recover to a previously ok state by storing which files were > involved in previous states, and giving the code some way of checking if they > are valid. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
