All work finished, thanks! [~weinan003] [~zhangshujie]
Form Weinan's mail in hawq-dev:
"At present, it supports 7 types of data trigger the vectorized function and
reach two to eight times
acceleration comparing with regular execution in different performance test
queries. Furthermore,
it has an extended friendly framework, you can patch other types into as your
need.
