Hi , I was a little unclear about this. I tried to use AirByte to transfer Salesforce data to BigQuery, but the table created in BigQuery had two additional columns for AirByte at the top. Is this something that is always added? And, it created a table that I did not intend to create. _airbyte_raw_Salesforce1_Account What is this used for?

Yes, they will always be added on all tables You can read more about this in the documentation, for example here (as well as the raw table): https://docs.airbyte.io/tutorials/connecting-el-with-t-using-sql#first-transformation-step-normalization
