How to configure Delta Lake on Azure as a destination in Mage to write data to a Delta table using ABFS.
Configuration Parameters
To use Delta Lake on Azure as a destination, provide the following parameters:
| Key | Description | Example Value | Required |
|---|---|---|---|
account_name | Your Azure Storage account name. This is the name of the account that hosts your Delta table. | myazurestorage | ✅ |
access_key | The access key for your Azure Storage account. Used to authenticate writes to your Delta table. | ABC123...XYZ | ✅ |
table_uri | URI for the Delta table. Must follow the abfs://<container>/<path> format. For more options, refer to the delta-rs docs. | abfs://my-container/delta/my-table | ✅ |
mode | Write mode. - append: Adds rows to the table. Errors if schema changes.- overwrite: Replaces all existing rows and recreates the table. | append (default) or overwrite | ✅ |
Notes
- The table URI must point to a valid Delta Lake table path accessible via Azure Data Lake Storage (Gen2) using the ABFS protocol.
- Mage uses the delta-rs engine for interacting with Delta Lake.
- If using
overwritemode, ensure downstream systems tolerate table recreation.
