> 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
> Priority: Major
> Labels: feature, variable
>
> 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 updates with
> non-valid JSON syntax 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.
