    Abstract: A data platform that implements memoizable functions for database objects. The data platform detects a first execution of a memoizable function and generates a first key based on metadata of one or more database objects operated on by the memoizable function and generates a first result for the memoizable function based on the one or more database objects. The data platform detects a second execution of the memoizable function and generates a second key based on the metadata of the one or more database objects operated on by the memoizable function. When the first key and the second key are equal, the data platform reuses the first result of the memoizable function. When the first key and second key do not match, the data platform generates a second result for the second execution of the memoizable function.

    Abstract: A method of sharing data in a multi-tenant database includes inspecting, by a processing device of a multiple tenant database, a sharer account to determine an existence of a link between an alias object in a target account and a database, wherein the database is linked to a first role object included in a share object in the sharer account. The method includes granting a second role object, in the target account, access rights to the alias object, wherein the first role object having one or more grants to one or more resources of the sharer account, and wherein the target account accesses the one or more resources using the one or more grants of the share object and using the alias object without at least one of copying the one or more resources or transmitting the one or more resources.

    Abstract: A method of sharing data in a multi-tenant database includes inspecting, by a processing device of a multiple tenant database, a sharer account to determine a presence of a grant to a second role object, in a target account, of access rights to a first role object included in the sharer account. The method includes granting the second role object, in the target account, access rights to an alias object. The first role object having one or more grants to the one or more resources of the sharer account. The target account accesses the one or more resources using the one or more grants of the first role object and using the alias object without at least one of copying the one or more resources or transmitting the one or more resources.
