  • Publication number: 20230237069
    Abstract: Techniques for database replication for a remote deployment include a method performed by a data platform executing instructions on at least one hardware processor. The method includes detecting receipt of a database replication request associated with a data consumer. The database replication request is requesting availability of an instance of a primary deployment database at a remote deployment of a data platform. In response to detecting the receipt of the database replication request, an account of a data provider at the remote deployment of the data platform is provisioned with a set of replication-preparation objects associated with the primary deployment database. A database refresh operation is invoked, causing database data be pushed from the primary deployment database to a database shell in the account of the data provider at the remote deployment, to create the instance of the primary deployment database.

  • Publication number: 20230214405
    Abstract: The embodiments described herein provide means for replicating external stages between deployments of e.g., a cloud data lake using a modified storage integration. The modified storage integration may be defined with a set of storage locations, wherein the storage integration comprises a base URL for each of the set of storage locations and wherein each storage location identifies a remote deployment where a cloud platform is hosted and a geographic region of the remote deployment. An external stage object may be bound to the storage integration, wherein the external stage object facilitates a data loading operation that is currently in progress on the first storage location. In response to detecting an outage at the first storage location, the data loading operation that was in progress on the first storage location may be continued at the second storage location using the storage integration.

  • Patent number: 11687506
    Abstract: Affinity-based listing recommendations are created and used in a public data exchange. Listings can be evaluated against one another for affinity or similarity such that users working with a particular dataset can be presented with other datasets that share an affinity. Affinity can be determined from both the dataset metadata as well as information from the dataset content. Calculation of affinity scores can be pre-computed and stored, in advance of use, or determined on-the-fly. Presentation of most-similar listings can be deterministic, can contain randomization, can employ time-decay, can be weighted, and can make use of a tiered-sum approach.

  • Publication number: 20230177210
    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.

  • Patent number: 11669630
    Abstract: A data dictionary generation system utilizes a background service that is programmed to automatically populate and update a data dictionary for listings offering shared data. A data dictionary includes metadata describing the shared data overall as well as the individual objects included in the listing, such as the individual tables, schemas, views, and functions. To generate the data dictionary, the data dictionary generation system analyzes the shared data to identify objects, identifies a set of data fields associated with each identified object and populates the set of data fields associated with each identified object based on the shared data offered by the listing. To ensure that a data dictionary for each listing remains up to date, the data dictionary generation system periodically scans the listings to identify any changes to share access granted to the listings.
