The Databend plugin for dbt (data build tool)

dbt-databend

The dbt-databend package contains all of the code enabling dbt to work with Databend.

Getting started

• Install dbt
• Read the introduction and viewpoint

Installation

Use your favorite Python package manager to install the app from PyPI, e.g.

python -m pip install dbt-databend

Supported features

Databend does not support a ALTER query for change a tables schema. So some features are not available.

• Table materialization
• View materialization
• Incremental materialization
• Seeds
• Sources
• Docs generate
• Tests
• Snapshots
• Ephemeral materialization

Database & schema

The dbt model database.schema.table is not compatible with Databend because Databend does not support a schema. So we use a simple model schema.table, where schema is the Databend's database.
