-------------------------------------
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.
