Clickhouse

ClickHouse is an open-source column-oriented database management system that enables high-performance real-time data analysis. As a development environment in Paradime, ClickHouse enables dbt™️ development from Paradime's Code IDE.

IP RESTRICTIONS

Make sure to allow traffic from one of the Paradime IPs in your firewall depending on the data location selected.

Setup Instructions

1. Click the gear Icon (⚙️) on the top right of the Paradime interface to access Account Settings

2. In the left sidebar, click "Connections"

3. Click "Add New" next to the Code IDE section

4. Select "ClickHouse"

5. In the Profile Configuration field, add at least these required parameters. For additional configuration options, see the Profile Fields Reference section below:

schema: dbt_transformations                    # Production database
host: clickhouse.internal.company.com          # Internal hostname
port: 9000                                     # Native protocol port
user: dbt_user                                 # Database user
password: clickhouse_pass_456                  # User password
secure: false                                  # Internal traffic
driver: native                                 # Native protocol

After adding the configuration, ensure it's properly formatted using a YAML formatter like YAML Formatter.

1. Provide a dbt™ Profile Name (This should match with the profile name set in your dbt_project.yml).

2. In the Target field, enter "dev". This is the default target your dbt project will use for development work.

3. The Threads value is pre-configured to 1, but you can adjust this number to specify how many parallel operations your dbt project can run.
