             Summary: Do not copy underlying HBase configuration when connection properties are supplied
                 Key: PHOENIX-2119
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2119
             Project: Phoenix
          Issue Type: Improvement
            Reporter: James Taylor


Related to PHOENIX-1958, we can avoid copying the underlying HBase configuration properties when connection properties are supplied by keeping an override maps on ConnectionQueryServices. In this case, a ReadOnlyProperty get will be first done on the override map and then subsequently on the base/shared map for the HBase configuration properties.

The reason to do this is because some applications always provide connection properties (usually for custom annotations that identify the tenant and request) and the memory overhead of copying *all* properties is too high.
