Abstract: Sharing data in a data exchange across multiple cloud computing platforms and/or cloud computing platform regions is described. An example computer-implemented method can include receiving data sharing information from a data provider for sharing a data set in a data exchange from a first cloud computing entity to a set of second cloud computing entities. In response to receiving the data sharing information, the method may also include creating an account with each of the set of second cloud computing entities. The method may also further include sharing the data set from the first cloud computing entity with the set of second cloud computing entities using at least the corresponding account of that second cloud computing entity.

Abstract: A data warehouse storing databases for a plurality of users, including service providers hosting data for other users of the data warehouse may implement a data exchange. A provider of data creates a listing in the exchange including metadata. A consumer browses the metadata and select a listing to add to consumed shares of the consumer. Browsing may be filtered to implement a private exchange. Adding of data may be limited by access controls requiring verification of the consumer's identity. The added data may be filtered to include only data that relates to the consumer. Sharing may be bi-directional such that a request to add a listing for first data of a provider may also reference second data of the consumer such that the first data is added to the consumed shares of the consumer and the second data is added to the consumed shares of the provider.

Abstract: Providing access to metrics on a private data exchange is described. An example computer-implemented method can include providing a data exchange by a cloud computing service on behalf of an entity. The data exchange may comprise several data listings provided by one or more data providers. The data listings reference one or more data sets stored in a data storage platform associated with the cloud computing service. The method may also include granting access the data listings, gathering consumer information based queries provided to data associated with the data listings, generating a new share comprising the consumer information, and granting access of the new share to the data provider that provided the data listing.

Abstract: Providing a private data exchange is described. An example computer-implemented method can include providing a data exchange by a cloud computing service on behalf of an entity. The data exchange may comprise several data listings provided by one or more data providers. The data listings reference one or more data sets stored in a data storage platform associated with the cloud computing service. The method may also include designating a data exchange administrator account of the data exchange. The data exchange administrator account may be associated with the entity and may be capable of: granting and denying requests from data consumers to access the data exchange; and granting and denying requests from data providers to publish data listings on the data exchange.

Abstract: Systems, methods, and devices for generating a secure join of database data are disclosed. A method includes determining data stored in a first account to be compared with data stored in a second account. The method includes determining a function for generating a secure join key, wherein the secure join key includes a hashed string that hashes one or more of a data entry of the first account and a data entry of the second account. The method includes providing the secure join key to the first account and/or the second account.

Abstract: Systems and methods for managing membership in a private data exchange are provided herein. In one embodiment, the method includes receiving a request for access to a first listing of a data exchange, each listing of the data exchange comprising version metadata. The method further includes, in response to the request, accessing a first version of a data set referenced by the first listing, wherein the first version of the data set comprises a first structure defined by first version metadata, a second listing of the data exchange references a second version of the data set, the second version of the data set comprising a second structure defined by second version metadata, and the second structure is incompatible with the first structure.

Abstract: Embodiments of the present disclosure may provide a data clean room allowing secure data analysis across multiple accounts, without the use of third parties. Each account may be associated with a different company or party. The data clean room may provide security functions to safeguard sensitive information. For example, the data clean room may restrict access to data in other accounts. The data clean room may also restrict which data may be used in the analysis and may restrict the output. The overlap data may be anonymized to prevent sensitive information from being revealed.

Abstract: Techniques described herein can monitor various data metrics. The auto-insight techniques can further detect and rank data segments that contributed to, or counteracted, shifts in data and detect when such shifts occurred. Thus, the techniques described herein can detect and identify root causes in shifts in different metrics. The techniques include pruning and ranking causes to identify the root causes and identify non-relevant factors, as well.

Abstract: Providing access to consumer information on a private data exchange is described. In an example, privileges are assigned to a share object, granting access to consumer information obtained from a query against data referenced by a data listing of a data exchange. The data exchange comprises one or more data listings provided by one or more data providers. In response to the share object being added to a list of consumed share objects of a data provider that provided the data listing, a database is generated that references the consumer information based on the share object. Access to the database is granted to the data provider that provided the data listing.
