Abstract: Techniques for identity resolution and data enrichment include instantiating, at an account of a data consumer, an identity resolution application using an installer stored procedure. A data object is configured, at the account of the data consumer, to share log data generated by the identity resolution application with an account of a data provider. The identity resolution application is enabled, at the account of the data consumer, for an identity resolution process using source data based on an instruction originating from the account of the data provider. The instruction is based on the configuring of the data object.

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: A search engine of a data exchange may receive a query comprising a set of search terms, retrieve a plurality of data listings based on the search terms of the query, compare a first embedding generated by a large language model (LLM) from the search query to second embeddings generated by the LLM for each of the plurality of data listings to determine a respective relevance for each of the plurality of data listings to the search query, and rank the plurality of data listings based on the respective relevance for each of the plurality of data listings to the search query.

Abstract: Embodiments of the present disclosure may provide a data clean room architecture that dynamically restricts data included in the clean room. The data clean room architecture can implement row access policy or dynamic data masking for row and column based restrictions of data provided through the clean room. The data clean room architecture can provide a limited set of data that does not require obfuscation of data for direction matching and correlation of data in the different datasets, such as matching user identifiers or emails.

Abstract: An advanced system for refining overlap queries in a database system based on user feedback. The system monitors interactions of a first user with a first dataset on the database system, where the first dataset is associated with the first user. Feedback regarding the quality of a results dataset, generated from an executed overlap query, is received from the first user. This feedback informs the generation of a similarity score dataset that enhances the creation of new overlap queries. These new overlap queries are designed to output refined overlap datasets between the first dataset and a second dataset associated with a second user. A new joined dataset is generated by executing these overlap queries, comprising data from both the first and second datasets. A new results dataset is generated, providing the first user with refined recommendations based on additional feedback.

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 creating a listing in a data exchange, the listing including a data set hosted by a first cloud computing entity. The data set can be shared with a second cloud computing entity. The method further includes receiving a request associated with a customer account of the second cloud computing entity to access the data set of the listing hosted by the first cloud computing entity and replicating at least a subset of the data set of the listing from the first cloud computing entity to a provider account at the second cloud computing entity to be accessible by the customer account at the second cloud computing entity.

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: Techniques for identity resolution and data enrichment include configuring, at an account of a data consumer, an outbound share. The outbound share is designating a share at an account of a data provider as a receiving share. An identity resolution application is instantiated at the account of the data consumer. An instruction originating from the account of the data provider is decoded at the account of the data consumer. The instruction is generated based on the configuring of the outbound share. The instruction enables the identity resolution application for an identity resolution process. Source data is retrieved from the account of the data provider at the account of the data consumer. The source data is associated with the identity resolution process.
