Abstract
Examples described herein provide a computer-implemented method for data lakehouse encryption that includes receiving a query for data stored in a data lakehouse. The method further includes determining whether the query is a frequent query by comparing a frequency of the query to a threshold. The method further includes, responsive to determining that the query is a frequent query, storing envelope encrypted data and a query index in a frequent data access database, the envelope encrypted data being data that relates to the query. The method further includes, responsive to receiving the query at a later time, returning, to a user, the envelope encrypted data from the frequent data access database without decrypting other data stored in the data lakehouse.
