------------------------------------------

             Summary: Add per-segment and per-commit id to help replication
                 Key: LUCENE-5895
                 URL: https://issues.apache.org/jira/browse/LUCENE-5895
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Michael McCandless
            Assignee: Michael McCandless
             Fix For: 5.0, 4.10
         Attachments: LUCENE-5895.patch

It would be useful if Lucene recorded a unique id for each segment written and each commit point.  This way, file-based replicators can use this to "know" whether the segment/commit they are looking at on a source machine and dest machine are in fact that same.

I know this would have been very useful when I was playing with NRT replication (LUCENE-5438).
