> 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.
