    sql cant use

    We are currently amidst a situation, where we want our Dashboard/chart owners to share their dashboard to only a specific set of user, to whom the owner decides to share it with (also some sort of audit for the owners to know who and all have access to dashboard ) .

    Version: 0.37.2
    Deployed: Google Kubernetes engine & on prem
    Authentication: Oauth
    Role: Custom role for all normal users (Gamma + sql lab role)
    Database: Connection to presto only
    Meta store : Postgres (stand alone outside Gke)

    Notes : Each user have their own unique database connection to the same presto . Hence the data source permissions for charts are assigned manually for now . We need to automate the permission
    Primary concern : The user should to whom the dashboard is shared should only have read access . also some sort of audit for the owners to know who and all have access to dashboard

    Hey, I am thinking about using apache superset, and I am wonder if it is the right tool to my use-case. I am working for a startup company, which is collecting unique data points, on top of that data we build data warehouse that has KPIs with an hierarchy. We want to build a self service dashboard as part of our offering to our users. Our system is designed to be multi-tenant, but the KPIS and measurements are general, but the data is unique for each tenant, and should be available only for the tenant account. We think that superset might help us with: 1. speeding up dashboard and widgets development using embedded dashboard. 2. Securing the the tenant data (using row level security). I just started my analysis and I don't have experience with superset in a production environment which is part of the customer critical path. Is anyone here as experience using sueprset in such a use-case? Thanks

    I playing with superset and i want to embed it inside an application for a demo, I am runing it using the docker-compose and it is working, but when i try to use the public dashboard approach i cant view the dashboard unless the user logs-in
    I have set the flag PUBLIC_ROLE_LIKE = "Gamma" and provided all required permissions in the public role, yet when i try to view the dashboard without logging in it fails with Unexpected Error

    Have a quick question on chart loading time improvements with redis caching activated. I have the following caching parameters setup in my superset_config.py file

        'CACHE_TYPE': 'redis',
        'CACHE_DEFAULT_TIMEOUT': 60 * 60 * 24,  # 1 day default (in secs)
        'CACHE_KEY_PREFIX': 'superset_results',
        'CACHE_REDIS_URL': 'redis://localhost:6379/0',
        'CACHE_TYPE': 'redis',
        'CACHE_DEFAULT_TIMEOUT': 60 * 60 * 24,  # 1 day default (in secs)
        'CACHE_KEY_PREFIX': 'superset_results',
        'CACHE_REDIS_URL': 'redis://localhost:6379/0',

    And tested this against the World bank's data dashboard. With an without caching, I am getting about 250 ~ 700 ms load time from watching the network response times in firefox for chart queries. Curious to see what performance numbers are others are seeing with caching on vs off

    I'm running a redis + postgres on a metal server and superset in docker.

    Hey is there a slack channel for Superset still?
    I want to share my thread on Twitter about how to build an Apache Superset dashbord with GSheet integration. This is an easy entry for data analysts or new users in Superset. It only requires Docker + Bash + SQL. Happy dashboarding! https://twitter.com/AldoEscobarLVP/status/1399708801163530241

    Hello, i am new with superset
    i am struggling to know the database used by superset to store its metadata (users, databases,...)
    i am using docker compose to launch superset
    where the connection parameters to the database are set?
    to see if i can query it easily
    and if also i can plugin it with another postgres database
    thank you for your precious help 🙂

    Hey guys, im currently trying to configure superset to use my custom Auhtorization Service (OAUTH2). My Service returns an access Token successfully but superset disregards the token I think, and starts the auhtorization process over and over again. Im stuck in a redirect loop. Do you have any Idea, why this is hapeninng?
    ahh figured it out - to impl custom oauth provider in superset you have to impl. userinfo getter in superset SecurityManager.
