Michael Dürig reopened OAK-6106:
--------------------------------
Reopening as there is a performance regression apparently introduced with these
changes.
> Excessive memory usage by the cached segment references
> -------------------------------------------------------
>
> Key: OAK-6106
> URL: https://issues.apache.org/jira/browse/OAK-6106
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Labels: perfomance
> Fix For: 1.7.0, 1.8
>
> Attachments: OAK-6106.patch

>
> The references of a segment to other segments are cached within
> {{Segment.readReferencedSegments()}}. However caching the {{SegmentId}}
> instances themselves leads to excessive heap usage as each id also keeps a
> reference to its underlying segment.
> I suggest to cache those references as msb, lsb pairs instead and create the
> {{SegmentId}} instance on the fly when required.
