[jira] [Created] (OAK-2945) Sampling rate feature CompactionGainEstimate is not efficient

Michael Dürig created OAK-2945:
----------------------------------

             Summary: Sampling rate feature CompactionGainEstimate is not efficient
                 Key: OAK-2945
                 URL: https://issues.apache.org/jira/browse/OAK-2945
             Project: Jackrabbit Oak
          Issue Type: Sub-task
          Components: segmentmk
            Reporter: Michael Dürig
            Assignee: Michael Dürig
             Fix For: 1.3.0, 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.
