Update or delete data from BigQuery


I have a process that reads from MySQL and uploads the data to BigQuery.

In order to execute this, I'm using tMysqlinput > tmap > tBigQueryInput

In certain conditions, I have to update or delete data from BigQuery.


I found this thread

But couldn't understand how to specify the data that I want to delete or update.



Do someone know what it the best way to update/ delete data from BigQuery, and how to connect it to tmap's output?
