What would you like to happen?

As an Apache Beam Python SDK developer, when wanting to write to BigQuery using its CDC capabilities, I would like to be able to configure:

• what is the row mutation information, so BigQuery can decide how to modify the data on the table
• and in case I want the table to be created, what is the primary key of the table data will be written to.
