* For some security concerns, you may need to enforce CSRF protection on all query request to explore_json endpoint. In Superset, we use `flask-csrf <https://sjl.bitbucket.io/flask-csrf/>`_ add csrf protection for all POST requests, but this protection doesn't apply to GET method.
* When ENABLE_EXPLORE_JSON_CSRF_PROTECTION is set to true, your users cannot make GET request to explore_json. The default value for this feature False (current behavior), explore_json accepts both GET and POST request. See `PR 7935 <https://github.com/apache/incubator-superset/pull/7935>`_ for more details.
* PRESTO_EXPAND_DATA
* When this feature is enabled, nested types in Presto will be expanded into extra columns and/or arrays. This is experimental, and doesn't work with all nested types.
