Bert Sanders commented on LUCENE-2446: -------------------------------------- Is CRC32 intrinsic available and the same on all relevant platforms ? (I assume it is CRC32C version of Intel) If not, what happens ? Does it still work ? Could it be a concern for performance-related issue ? > Add checksums to Lucene segment files > ------------------------------------- > > Key: LUCENE-2446 > URL: https://issues.apache.org/jira/browse/LUCENE-2446 > Project: Lucene - Core > Issue Type: Improvement > Components: core/index > Reporter: Lance Norskog > Labels: checksum > Attachments: LUCENE-2446.patch > > > It would be useful for the different files in a Lucene index to include > checksums. This would make it easy to spot corruption while copying index > files around; the various cloud efforts assume many more data-copying > operations than older single-index implementations. > This feature might be much easier to implement if all index files are created > in a sequential fashion. This issue therefore depends on [LUCENE-2373]. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
