Native multi-tenant encryption for database system

A method comprising:

• storing, in a memory:
• metadata defining a tenant object and a plurality of database artifacts;
• a first instance of the tenant object;
• a first plurality of the database artifacts associated with the first instance and including first data associated with the first instance of the tenant object;
• a second instance of the tenant object;
• and
• a second plurality of the database artifacts associated with the second instance and including second data associated with the second instance of the tenant object;
• and
• encrypting the first data associated with the first instance of the tenant object using a first public encryption key and storing the encrypted first data in a persistent storage system;
• and
• encrypting the second data associated with the second instance of the tenant object using a second public encryption key and store the encrypted second data in the persistent storage system.

A non-transitory computer-readable medium storing program code executable by one or more processing units to cause a computing system to:

• store, in a memory:
• metadata defining a tenant object and a plurality of database artifacts;
• a first instance of the tenant object;
• a first plurality of the database artifacts associated with the first instance and including first data associated with the first instance of the tenant object;
• a second instance of the tenant object;
• and
• a second plurality of the database artifacts associated with the second instance and including second data associated with the second instance of the tenant object;
• and
• encrypt the first data associated with the first instance of the tenant object using a first public encryption key and storing the encrypted first data in a persistent storage system;
• and
• encrypt the second data associated with the second instance of the tenant object using a second public encryption key and store the encrypted second data in the persistent storage system.
