> Key: OAK-4669
> URL: https://issues.apache.org/jira/browse/OAK-4669
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Affects Versions: Segment Tar 0.0.8
> Reporter: Andrei Dulceanu
> Assignee: Andrei Dulceanu
> Priority: Minor
> Labels: cleanup, gc
> Fix For: Segment Tar 0.0.10
>
> Attachments: test case.patch
>
>
> On some deployments I have seen tar files with a quite hight generation
> post-fix (e.g. 'v'). From the log files I could deduce that this particular
> tar file was rewritten multiple times without actually any segment being
> removed.
> I assume this is caused by the 25% gain threshold not taking the sizes
> contributed by the index and the graph entries into account.
> The attached test case can be used to verify the above hypothesis
