Zusammenfassung:Methods, systems, and computer-readable storage media for selecting columns for re-encryption in join operations. In some implementations, actions include determining a first column and a second column to be joined, receiving a first key corresponding to the first column and a second key corresponding to the second column, receiving a first rank associated with the first key and a second rank associated with the second key, selecting the second column for re-encryption based on the first rank and the second rank, and providing the first column, the second column, and the first key for performing a join operation, the second column being re-encrypted based on the first key.
