             Summary: More efficient CoreValues
                 Key: OAK-152
                 URL: https://issues.apache.org/jira/browse/OAK-152
             Project: Jackrabbit Oak
          Issue Type: Improvement
          Components: core
            Reporter: Jukka Zitting
            Assignee: Jukka Zitting
            Priority: Minor


The current CoreValueImpl needs two Java objects per value, one for the CoreValueImpl instance and another for the referenced value object. It also needs an extra int field to store the value type.

Type-specific value classes could avoid the type field and the extra value object for the primitive types (long, double, boolean).

We could further reduce memory overhead by maintaining a set of flyweight instances of commonly occurring values (small numbers, common JCR names, etc.).
