[jira] [Created] (OAK-5046) Remove the old estimation OSGi setting
(compaction.gainThreshold)
Andrei Dulceanu created OAK-5046:
------------------------------------
Summary: 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
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.
