Flask-AppBuilder permissions

Superset uses the Flask-AppBuilder framework to store metadata required for permissions in Superset. Every time a Flask-AppBuilder app is initialized, permissions and views are automatically created for the Admin role. When multiple concurrent workers are started by Gunicorn, they might lead to contention and race conditions between the workers trying to write to one metadata database table.

The automatic updating of permissions in the metadata database can be disabled by setting the value of the SUPERSET_UPDATE_PERMS environment variable to zero. It is one or enabled by default:

export SUPERSET_UPDATE_PERMS=1 superset init
# Make sure superset init is called before Superset starts with a new metadata database
export SUPERSET_UPDATE_PERMS=0 gunicorn -w 10 … superset:app
