Andrei Dulceanu commented on OAK-5046:
--------------------------------------
Per [~alexparvulescu]'s suggestion, currently the focus is only to tidy up the
OSGi configs, without removing any code. [~mduerig], WDYT?
> Remove the old estimation OSGi setting (compaction.gainThreshold)
> -----------------------------------------------------------------

> Key: OAK-5046
> URL: https://issues.apache.org/jira/browse/OAK-5046
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-tar
> Affects Versions: 1.5.12
> Reporter: Andrei Dulceanu
> Assignee: Andrei Dulceanu
> Priority: Minor
> Labels: osgi-config
> Fix For: 1.5.13
>
>
> Currently, there are two implementations for finding out the gain in
> repository size after running compaction: the old one,
> {{CompactionGainEstimate}} and the new one, {{SizeDeltaGcEstimation}}.
> Similarly, there are also two configurations for customising them, in
> {{SegmentNodeStoreService}}, {{compaction.gainThreshold}} and
> {{compaction.sizeDeltaEstimation}}.
> At the moment both of them are exposed as OSGi configurations, but only the
> new one should be exposed (e.g. {{compaction.sizeDeltaEstimation}}).
> It must be evaluated whether it makes sense to keep the logic associated with
> the old implementation.
