> 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.
