Using components: Google BigQuery Source

Use the Google BigQuery source component to read data stored in an Google BigQuery table or using a query.


Select an existing Google BigQuery connection or create a new one. For more information, see Allowing ETL access to my Google BigQuery dataset.

Source Properties

  • Access mode - select table to extract an entire table or query to execute a query (access table views).
  • Source table - the table name from which the data will be imported.
  • Query - type in a SQL query. Make sure to name all columns uniquely. 

Source Schema

After defining the source table/query select the fields to use in the source.

With table access mode, the fields you select are used to build the query that will be executed to read the data.

With query access mode, select all the fields that are defined in the query and make sure to use the same column names

Define the data type for the field. Use the following table when matching BigQuery data types to ETL data types.
