Personal Data in Pipelines

Personal data is any information that relates to a person who is named, or who could be named by combining it with other information. The European Union's General Data Protection Regulation (GDPR) defines it as "any information relating to an identified or identifiable natural person". California's Consumer Privacy Act (CCPA) uses the term personal information for information that "identifies, relates to, or could reasonably be linked with you or your household."

Both definitions are about the person, not about a type of column
