             Summary: First class support for JSON variables
                 Key: AIRFLOW-310
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-310
             Project: Apache Airflow
          Issue Type: Wish
            Reporter: Bence Nagy


Looking at our variables, every single one of them is JSON, the largest being 100 lines long. I will assume that most other users are mainly using JSON vars as well.

I can think of a few quality of life changes that could be made to make working with these variables easier:

 - Make the 'Val' field on {{/admin/variable/edit}} use a fixed width font. This would probably not hurt non-JSON users either.
 - Add JSON syntax highlighting to the textarea there.
 - Add optional JSON syntax validation; perhaps a boolean flag in the DB for whether the var is supposed to be JSON. If true, reject non-valid updates to the variable, and perhaps don't require {{deserialize_json=True}} to be specified in the code every time it's accessed.
 - This last one might be a bit far-fetched, but: Make it possible to add a [JSON schema file|http://json-schema.org/] that will be validated against on updates.

Let me know if you want these split into separate JIRA issues.
