Techniques herein enable a tenant of a multi-tenant database to select a programming language to interact with a platform that uses a default programming language. A tenant-specific engine may manage a runtime context associated with the tenant in which a tenant may input code that is translated into the default programming language and executed. During execution, the tenant-specific engine may enforce various multi-tenant protections associated with the tenant. For example, the tenant-specific engine may monitor the runtime context and operations of the translated code, and may enforce computational limitations of the tenant as the translated code is executed.
