          Components: Query Processor
            Reporter: Ning Zhang


External tables are extremely useful when two or more tables share the same data but would
like to avoid the data copy and ownership conflicts. We found it useful to extend the "external"
concept to the partition level: some partitions of a managed table could be external, so that
dropping an external partition won't delete the data.
