    Abstract: In an embodiment, a data platform creates an application in a data-provider account. The application includes one or more APIs corresponding to one or more underlying code blocks. The data platform shares provider data with the application in the data-provider account, and also installs, in a data-consumer account, an application instance of the application. The application instance includes one or more APIs corresponding to the one or more APIs in the application in the data-provider account. The data platform shares consumer data with the application instance in the data-consumer account, and invokes one or more of the APIs of the application instance to execute respective associated underlying code blocks, which are not visible to the data-consumer account. The data platform also saves output of the one or more respective associated underlying code blocks locally within the data-consumer account.

    Abstract: A data platform creates an application in a data-provider account, where the application includes one or more application programming interfaces (APIs) corresponding to one or more underlying code blocks. The data platform shares homomorphically encrypted provider data with the application in the data-provider account. The data platform installs, in a data-consumer account, an application instance of the application. The data platform shares homomorphically encrypted consumer data with the application instance in the data-consumer account. The data platform invokes one or more of the APIs of the application instance to execute respective associated underlying code blocks, which are not visible to the data-consumer account, and which operate on the shared homomorphically encrypted provider data and the shared homomorphically encrypted consumer data. The data platform saves homomorphically encrypted output of the one or more respective associated underlying code blocks locally within the data-consumer account.

    Abstract: Systems, methods, and devices for implementing secure views for zero-copy data sharing in a multi-tenant database system are disclosed. A method includes generating a share object in a first account comprising a share role. The method includes associating view privileges for the share object such that an underlying detail of the share object comprises a secure view definition. The method includes granting, to a second account, cross-account access rights to the share role or share object in the first account. The method includes receiving a request from the second account to access data or services of the first account and providing a response to the second account based on the data or services of the first account. The method is such that the underlying detail of the share object that comprises the secure view definition is hidden from the second account and visible to the first account.

    IPC: G06F16/2453

    Abstract: Queries executed against a materialized view can execute up to orders of magnitude faster than equivalent queries on a source (or base) table. However, although a query can reference a materialized view directly, a user (e.g., query author) may not know about a relevant materialized view. Moreover, if a source table has multiple materialized views generated, the user may not know which materialized view to reference in the query. Thus, embodiments of the present disclosure provide techniques for automatically rewriting queries directed to a source table to utilize existing materialized views.

    Abstract: Systems, methods, and devices for secure view-based data sharing are disclosed. A method in accordance with embodiments disclosed herein comprises associating, by one or more processors, view privileges of a secure view with one or more of a plurality of underlying details of a share object of a first account such that each of the one or more underlying details of the share object comprises a definition of the secure view. The method further comprises: in response to receiving a request from a second account to access any underlying details of the share object, using a secure projection that does not match any rewrite rule preconditions to rewrite a query plan of the request to prevent expressions that do not originate from the secure view from being pushed down below a boundary of the secure view.
