Connecting to DuckDB with dbt-duckdb

DuckDB is an embedded database, similar to SQLite, but designed for OLAP-style analytics instead of OLTP. The only configuration parameter that is required in your profile (in addition to type: duckdb) is the path field, which should refer to a path on your local filesystem where you would like the DuckDB database file (and it's associated write-ahead log) to be written. You can also specify the schema parameter if you would like to use a schema besides the default (which is called main).

There is also a database field defined in the DuckDBCredentials class for consistency with the parent Credentials class, but it defaults to main and setting it to be something else will likely cause strange things to happen that cannot be fully predicted, so please avoid changing it.

Example:

profiles.yml
your_profile_name:
target: dev
outputs:
dev:
type: duckdb
path: 'file_path/database_name.duckdb'
#optional fields
schema: schema_name
