[jira] [Updated] (OAK-2946) Sampling rate feature
CompactionGainEstimate is not efficient
[ https://issues.apache.org/jira/browse/OAK-2946?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

----------------------------------
Fix Version/s: 1.4
> Sampling rate feature CompactionGainEstimate is not efficient
> -------------------------------------------------------------
>
> Key: OAK-2946
> URL: https://issues.apache.org/jira/browse/OAK-2946
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segmentmk
> Reporter: Michael Dürig
> Assignee: Michael Dürig
> Labels: compaction, gc
> Fix For: 1.3.0, 1.4, 1.0.15

> The sampling rate feature introduced with OAK-2595 is not efficient. It only prevents uuids from being stored in the bloom filter while the visited set is not affected and thus keeps growing.
> I will remove the feature again for now. We should look for a better solution once this becomes a problem. Will follow up on OAK-2939 re. this.
