    Abstract: Embodiments of the present disclosure may provide a data clean room allowing secure data analysis across multiple accounts and across different regions and cloud providers. 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. A version of a provider account can be created that is similar to a client account, such as in the same cloud type or the same region as the client database account. The client account can share data that is replicated to the provider account to complete client requests using an anonymized data and the cross reference table.

    Abstract: Systems, methods, and devices for generating a secure join of database data are disclosed. A method creates a secure view of datapoints of a consumer account and processes, using a secure user defined function (UDF), the datapoints of the consumer account and datapoints of a provider account to generate a secure join key. The datapoints of the consumer account are provided to the secure UDF using the secure view. The method further performs, by a processor, an analysis of the datapoints of the consumer account and the datapoints of the provider account of the secure join key. The analysis returns a count value of overlapping datapoints between the consumer account and the provider account. The method further adjusts the count value of overlapping datapoints based on a number of distinct rows associated with the provider account, and provides the adjusted count value of overlapping datapoints to the consumer account.

    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.
