[jira] [Created] (OAK-5250) Avoid temporary files on re-index

Marcel Reutegger created OAK-5250:
-------------------------------------

             Summary: Avoid temporary files on re-index
                 Key: OAK-5250
                 URL: https://issues.apache.org/jira/browse/OAK-5250
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: lucene
            Reporter: Marcel Reutegger
             Fix For: 1.8


A lucene index with copy-on-write writes back files to the repository asynchronously and the implementation may skip files that are created on the local filesystem and shortly after deleted again. For the re-index case this could be further improved. All intermediate lucene segment files that are later merged together can be skipped if the asynchronous write back is disabled and only the final files are copied to the repository when the directory is closed. This would avoid a lot of garbage in the blob store.
