Hi Yujun,

Good job! This is a very important change for Vitrage.

I have a couple of questions please:
1. Why do we want to create a new datasource ‘static’ and not rename the 
current ‘static_physical’ datasource and change it to work with the new format?
2. How are you planning to use the old 'static_physical' datasource  as a proxy 
if you said that you want to remove it?
3. What kind of merge is needed in the evaluator?
4. I saw the implementation of the driver.py in static, and it doesn't do 
anything at the moment? (if you are still working on one of the patches then 
please market it as -1 in the code-review that we will know that you are still 
working on it.)

BR,
Alexey

bp:static-datasource-config-formatworking items

Hi folks.

I have just started working on the blueprint about static datasource config 
format[1]. The planned working items are as following.
1. create new datasource `static` to parse new configuration format
2. parse old configuration format in `static` with a proxy to existing 
`static_physical` module
3. remove `static_physical` datasource and print deprecation warning in `static`
4. merge common logic with scenario template evaluator
Requesting for comments.

P.S. I chose the name `static` since it is actually not limited to physical 
entities. Virtual entities can also be described in `static` file if there is 
no dynamic source.
