MotherDuck
DuckDB is an in-process SQL OLAP database management system and this destination is meant to use locally if you have multiple smaller sources such as GitHub repos, some social media and local CSVs or files you want to run analytics workloads on. This destination writes data to the MotherDuck service, or to a file on the local filesystem on the host running Airbyte.
For file-based DBs, data is written to /tmp/airbyte_local by default. To change this location, modify the LOCAL_ROOT environment variable for Airbyte.
This destination implements Destinations V2, which provides improved final table structures. It's a new version of the existing DuckDB destination and works both with DuckDB and MotherDuck.
Learn more about what's new in Destinations V2 here.
This DuckDB destination is compatible with MotherDuck.
To specify a MotherDuck-hosted database as your destination, simply provide your database uri with the normal md: database prefix in the destination_path configuration option.
We do not recommend providing your API token in the md: connection string, as this may cause your token to be printed to execution logs. Please use the MotherDuck API Key setting instead.
For authentication, you will use your MotherDuck Access Token.
Each table will contain at least the following columns:
_airbyte_raw_id: a uuid assigned by Airbyte to each event that is processed._airbyte_extracted_at: a timestamp representing when the event was pulled from the data source._airbyte_meta: a json blob storing metadata about the record.
In addition, columns specified in the JSON schema will also be created.
| Feature | Supported | |
|---|---|---|
| Full Refresh Sync | Yes | |
| Incremental - Append Sync | Yes | |
| Incremental - Append + Deduped | Yes | |
| Typing and Deduplication | Yes | |
| Namespaces | No | |
| Data Generations | No |
This integration will be constrained by the speed at which your filesystem accepts writes.
This connector is primarily designed to work with MotherDuck and local DuckDB files for Destinations V2. If you would like to work only with local DuckDB files, you may want to consider using the DuckDB destination.
