> 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
> Labels: performance
>
> 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.
