    how can i format the numbers for my superset dashboard? instead of 10000 i have 10,000
    Bastien Vial-Collet
    Hi all. I have the same question as @billy-odera . When displaying raw data in a table chart, I can't find a way to format the numbers except by creating metrics. This is not what I want as I don't want to agregate.
    Thanks in advance.
    I've just installed superset from docker. I'm trying to user current user id in a query without success: select '{{current_user_id()}}'what am i doing wrong? The result I get is '{{current_user_id()}}' without value substitution
    Hi, i just installed superset on my linux server using docker, but when i try to access it, i got error like this "sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not translate host name "db" to address: Name or service not known",
    i already search throughout internet but no one that can solve my problem
    this error dissapear when i re-start my docker-compose, but after couple of times that error come again

    hi, i make a pie chart with datetime data but a value is 14985701929 not a date time. what should i do ??
    @rajeshchy Have you got any solution for the problem? I need this too.
    Michael Rea
    @billy-odera @vialcollet we have the the same need. I think there's a feature request logged for this, but there's no way to currently do it without creating a metric.

    Hi guys. My table cannot be loaded more than 10k rows. How can I increase the memory in superset? I already switched to a machine with 2 CPU and 4 GB RAM to 8 CPU and 32GB RAM.

    I feel like I am missing something, I have added sqlalchemy-redshift package to the docker/requirements-local.txt but I am still getting ERROR: Could not load database driver: RedshiftEngineSpec when testing connection ; any help on how to debug this would be awesome :)

    Hi, I'm using Superset with Postgres and trying to run "SET TIME ZONE" to set the user's timezone prior to the query. I've tried appending in the SQL_QUERY_MUTATOR in config.py but SQL Alchemy rejects it as an invalid query. Any suggestions on how to do this?

    HI, does anyone know about multiplier and javascript data interceptor in deck.gl scatterplot superset?

    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 🙂
