ClickHouse
To use ClickHouse with Superset, you will need to add the following Python libraries:
clickhouse-driver==0.2.0
clickhouse-sqlalchemy==0.1.6
If running Superset using Docker Compose, add the following to your ./docker/requirements-local.txt
file:
clickhouse-driver>=0.2.0
clickhouse-sqlalchemy>=0.1.6
The recommended connector library for ClickHouse is sqlalchemy-clickhouse.
The expected connection string is formatted as follows:
clickhouse+native://<user>:<password>@<host>:<port>/<database>[?options…]clickhouse://{username}:{password}@{hostname}:{port}/{database}
Here's a concrete example of a real connection string:
clickhouse+native://demo:demo@github.demo.trial.altinity.cloud/default?secure=true
If you're using Clickhouse locally on your computer, you can get away with using a native protocol URL that uses the default user without a password (and doesn't encrypt the connection):
clickhouse+native://localhost/default
