About This Task

Druid and Superset require a relational data store to store metadata. To use Postgres for this, install Postgres and create a database for the Druid metastore. If you have already created a data store using MySQL, you do not need to configure additional metadata stores in Postgres.

Steps

1. Log in to Postgres:

    sudo su postgres
    psql

2. Create a database, user, and password, each called druid, and assign database privileges to the user druid:

    create database druid;
    CREATE USER 'druid' WITH PASSWORD 'druid';
    GRANT ALL PRIVILEGES ON DATABASE "druid" to druid;

3. Create a database, user, and password, each called superset, and assign database privileges to the user superset:

    create database superset;
    CREATE USER 'superset' WITH PASSWORD 'superset';
    GRANT ALL PRIVILEGES ON DATABASE "superset" to superset;
