Configure Druid and Superset Metadata Stores in Postgres

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

Log in to Postgres:
```
sudo su postgres
psql
```
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;
```
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;
```
