Abstract

In privacy restrictions for columnar storage, a query including operations on one or more protected columns is received. The one or more protected columns are specified with one or more access restricting metadata in a columnar table. It is determined whether the received query comprises operations on the one or more protected columns specified with the one or more access restricting metadata. The execution of the query is restricted and a constraint violation is displayed, based on the determination.
