Abstract: Provided herein are systems and methods for providing a secure and efficient way to manage a data exchange's availability and manage the visibility of data listings of the data exchange. For example, the method may comprise specifying, by an exchange admin of the data exchange, a set of regions where the data exchange is available, each of the set of regions comprising one or more remote deployments. The method may further comprise specifying by a data provider, one or more of the set of regions where a data listing owned by the data provider is visible. Upon receiving a request to access the data listing from a remote deployment of the one or more regions, the data provider may determine whether to reject or fulfill the request. In response to determining that the request should be fulfilled, replicating data of the data listing to the remote deployment.

Abstract: A system for sub-table replication within a materialized view of a source data table. A materialized view of a source data table is generated based on a query, the source data table having a plurality of data table rows associated with a plurality of client identifiers and including an entitlements column and data content, the entitlements column including a plurality of provider account identifiers and a plurality of consumer account identifiers. An update to an entitlements table of the source data table is detected where the entitlements table includes a plurality of entitlements table rows and where the entitlements table rows are associated with the client identifiers, the consumer account identifiers, and the provider account identifiers. An update to the source data table based on the first update to the entitlements table is detected, and an incremental replication of the materialized view of the source data table is performed.

Abstract: Sharing data in a data exchange across multiple cloud computing platforms is described. An example method can include copying, to a first cloud computing entity using a consumer account of the first cloud computing entity, a first subset of a data set associated with a provider account of a second cloud computing entity, wherein the provider account of the second cloud computing entity does not have access to the first cloud computing entity, and then copying, to a third cloud computing entity using a consumer account of the third cloud computing entity, a second subset of the data set, wherein the provider account of the third cloud computing entity does not have access to the first cloud computing entity, for which the first subset of the data set is different from the second subset of the data set.

Abstract: Provided herein are systems and methods for replicating share objects to remote deployments. An example method includes generating, at a second deployment in a data exchange, a replica of a share object included in a first deployment of the data exchange. The share object grants privileges to a first account to access a first database of the first deployment, wherein the first database comprises a database object. The method also includes retrieving, at the first deployment, share grant metadata from the share object of the first deployment, wherein the share grant metadata includes a reference to the database object and allows the first account to use the database object. The method also includes transmitting a message comprising the share grant metadata to the replica in the second deployment. The share grant metadata in the replica allows a second account to use the database object replicated in the second deployment.

Abstract: A method of implementing sub-table replication starts with the processor detecting an update to an entitlements table. The processor performs filtering of a data table based on the update to the entitlements table. The data table including an entitlements column. The processor detects an update to the entitlements column and performs incremental replication of the data table by causing a version-based replication to be executed. Other embodiments are also described herein.

Abstract: Sharing data in a data exchange across multiple cloud computing platforms and/or cloud computing platform regions is described. An example method can include generating a consumer account corresponding to a first cloud entity and receiving, by the first cloud entity, a copy of a data set from a provider account corresponding to a second cloud computing entity, wherein the first cloud computing entity and the second cloud computing entity represent different regions of a cloud computing platform. The method may also include accessing, by the consumer account, the copy of the data set.

Abstract: Systems and methods for managing membership in a private data exchange are provided herein. In one embodiment, the method includes generating a plurality of listings in a data exchange. A first listing of the plurality of listings may include a reference to a first version of shared data within a first database, where the first version is one of a plurality of versions of the shared data within the first database. The method further includes receiving a request from a member of the data exchange for access to the first listing and limiting, by a processing device, access for the member to the first version of the shared data of the first database referenced by the first listing.

Abstract: A method of operating a data exchange includes creating a first listing referencing data of a first database of a plurality of databases, wherein the first listing comprises access controls and a data share associated with a first user, the access controls defining portions of the first database that are accessible by a second user, receiving a request from the second user for a bidirectional share between the portions of the first database that are accessible by the second user and portions of a second database controlled by the second user, and receiving an instruction from the first user to perform a database operation referencing data of the bidirectional share between the portions of the first database that are accessible by the second user and the portions of the second database controlled by the second user.
