Exporting Data to BigQuery
Infoworks supports BigQuery as a target in data transformation pipelines. This helps data engineers onboard data to BigQuery. |
Prerequisite
Ensure that the BigQuery target data connection is configured. For more details, see Setting BigQuery Data Connection.
Setting BigQuery Target Properties
Following are the steps to use BigQuery target in the pipeline:
- Double-click the BigQuery Table node. The properties page is displayed.
- Click Edit Properties, and set the following fields:
| Field | Description |
|---|---|
| Build Mode | The options include overwrite, append, or merge. Overwrite: Drops and recreates the BigQuery target. Append: Appends data to the existing BigQuery target. Merge: Merges data to the existing table based on the natural key. |
| Data Connection | Data connection to be used by the BigQuery target. For more details, see Setting BigQuery Data Connection. |
| Dataset Name | Dataset name of the BigQuery target. |
| Create a dataset if it does not exist | Enable this option to create a new schema with the name provided above. Ensure that the user has sufficient privileges to create a dataset in BigQuery target. |
| Table Name | Table name of the BigQuery target. |
| Natural Keys | The required natural keys for the BigQuery target. |

| Start | The start value for the partition of data. This field is displayed for integer column partition type. |
| End | The end value for the partition of data. This field is displayed for integer column partition type. |
| Range | The range for the partition of data. This field is displayed for integer column partition type. |
| Clustering Columns | The columns to be used for clustering. You can select up to 4 columns. |
