[jira] [Created] (LUCENE-8734) nextWriteDelGen of SegmentCommitInfo should be persisted

Nhat Nguyen created LUCENE-8734:
-----------------------------------

             Summary: nextWriteDelGen of SegmentCommitInfo should be persisted
                 Key: LUCENE-8734
                 URL: https://issues.apache.org/jira/browse/LUCENE-8734
             Project: Lucene - Core
          Issue Type: Bug
          Components: core/index
    Affects Versions: 8.0, 7.7.1
            Reporter: Nhat Nguyen
            Assignee: Nhat Nguyen


When opening an IndexWriter, we will set nextWriteDelGen, nextWriteFieldInfosGen, and nextWriteDocValuesGen beyond what we have in the directory to avoid double writes in cases where the previous IW was not closed gracefully or the new IW is opened with a previous commit (not the latest commit). We need to persist these values; otherwise, they will be lost when the current IW is closed.
