[jira] [Created] (OAK-2927) ReferenceEditor newIds cosuming lots of memory during migration

Chetan Mehrotra created OAK-2927:
------------------------------------

             Summary: ReferenceEditor newIds cosuming lots of memory during migration
                 Key: OAK-2927
                 URL: https://issues.apache.org/jira/browse/OAK-2927
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core
            Reporter: Chetan Mehrotra
            Priority: Minor
             Fix For: 1.3.0, 1.2.3, 1.0.15


In a large migration its seen that {{ReferenceEditor}} {{newIds}} can consume lots of memory as it records all the uuid property. This system has 33 million uuid index and the set was consuming ~1.5G of memory

We should look into ways such that it does not have to maintain such a big in memory state
