---------------------------------

             Summary: Include Pluggable Storage Format Framework in External Table Scan
                 Key: HAWQ-1565
                 URL: https://issues.apache.org/jira/browse/HAWQ-1565
             Project: Apache HAWQ
          Issue Type: Sub-task
          Components: External Tables, Storage
            Reporter: Chiyang Wan
            Assignee: Radar Lei


There are 2 types of operation related to external table, i.e. scan, insert(also related to
copy from). Including pluggable storage framework in these operations is necessary. 

Moreover, we plan to rewrite the tuple construct and consume working flow in the external
table, which leads to data copy cost. 

In the following steps, we still need to specify some of the critical info that comes from
the planner and the file splits info in the pluggable filesystem.
