---------------------------------
Summary: Refactor resource related GUC.
Key: HAWQ-497
URL: https://issues.apache.org/jira/browse/HAWQ-497
Project: Apache HAWQ
Issue Type: Bug
Components: Core
Reporter: Hubert Zhang
Assignee: Lei Chang
we have confusing GUCs to control how many vsegs a query will use. It's better
to remove the default_segment number and replace it with other meaningful GUCs.
And we need to expose as less GUCs as possible to users, which let performance
tuning become easy.
