---------------------------------
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.
