  • Publication number: 20230244695
    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.

  • Publication number: 20230244642
    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.

  • Patent number: 11645244
    Abstract: Provided herein are systems and methods for an efficient method of replicating share objects to remote deployments. An example method includes receiving, at a first deployment in a data exchange, a refresh message from a second deployment in the data exchange, wherein the first deployment comprises a database that stores a database object. The method also includes, in response to receiving the refresh message, retrieving, at the first deployment, a share grant from a share object of the first deployment and transmitting, by a processing device of the first deployment, a message including the share grant to the second deployment. The share grant includes a reference to the database object and allows a consumer to use the database object.

  • Patent number: 11461285
    Abstract: Provided herein are systems and methods for an efficient method of replicating share objects to remote deployments. For example, the method may include generating a global representation of a share object of a first database account located in a first region. The share object includes grant metadata associated with a set of objects of a database located in the first region and associated with the first database account. The method may further include, in response to a database refresh command received from a second database account associated with a database replica located in a second region, replicating the set of objects of the database to the database replica. The method may further include, in response to a share refresh command received from the second database account, replicating the grant metadata to a share object replica located in the second region.
