Abstract: Embodiments of the present disclosure provide systems and methods for defining database roles to allow sharing of the objects within a database in a more granular fashion. A database role is created within a database, and privileges are granted to the database role by a provider account. The database role may be granted to a share object, which would result in the share object being indirectly granted all privileges that have been granted to the database role. Once the share object has been hydrated in the consumer account, the local administrator can then decide which local roles are granted usage on the shared database role, thus ultimately allowing some level of filtering as to which shared objects can be accessed by which local roles.

Abstract: Example systems and methods for cloning catalog objects are described. In one implementation, a method identifies an original catalog object associated with data and creates a duplicate copy of the original catalog object without copying the data itself. The method allows access to the data using the duplicate catalog object and supports modifying the data associated with the original catalog object independently of the duplicate catalog object. The duplicate catalog object can be deleted upon completion of modifying the data associated with the original catalog object.

Abstract: Disclosed herein are systems and methods for selective scanning of external partitions. In an embodiment, a database platform receives a query directed at least in part to an external table stored on an external data storage platform. The external table is partitioned into partitions corresponding to storage locations in the external data storage platform. The database platform prunes, using external-table metadata that is stored by the database platform and that maps the partitions of the external table to the storage locations in the external data storage platform, those partitions that do not potentially contain data that satisfies the query. The database platform identifies data that satisfies the query by scanning any one or more of the partitions of the external table that were not pruned, and responds to the query at least in part with the identified data that satisfies the query.

Abstract: Providing access to metrics on a private data exchange is described. An example computer-implemented method can include executing one or more queries against data referenced by a data listing of a data exchange, the data exchange comprising a plurality of data listings provided by one or more data providers, gathering consumer information based on the one or more queries, assigning privileges that grant access to the consumer information to a share object, in response to the share object being added to a list of consumed share objects of a data provider that provided the data listing, generating a database that references the consumer information based on the share object, and granting access to the database to the data provider that provided the data listing.

Abstract: Example resource management systems and methods are described. In one implementation, a resource manager is configured to manage data processing tasks associated with multiple data elements. An execution platform is coupled to the resource manager and includes multiple execution nodes configured to store data retrieved from multiple remote storage devices. Each execution node includes a cache and a processor, where the cache and processor are independent of the remote storage devices. A metadata manager is configured to access metadata associated with at least a portion of the multiple data elements.

Abstract: A database platform receives an object identifier from a client in association with a database session. The client is associated with a customer account of the database platform, and the database session is associated with the client. The customer account includes multiple disjoint account-level namespaces, each of which represents a distinct context for resolution of object identifiers, such that matching object identifiers in different account-level namespaces in the customer account do not collide with respect to object-identifier resolution. The database platform determines that the object identifier does not specify an account-level namespace, and responsively resolves the object identifier with reference to a current account-level namespace of the database session by identifying an object corresponding to the object identifier in the customer 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: Example resource management systems and methods are described. In one implementation, a resource manager is to be coupled to one or more virtual data warehouse instances that each comprise a plurality of computing resources. A resource manager receives a query directed to database data. The resource manager determines a plurality of tasks associated with the query. The resource manager distributes the plurality of tasks among the one or more virtual data warehouse instances to cause each computing resource of the plurality of computing resources of the one or more virtual data warehouse instances to process a respective task of the plurality of tasks. The resource manager receives results obtained from the processing of the plurality of tasks. The resource manager uses the results to respond to the query.

Abstract: Systems, methods, and devices for executing a task on database data in response to a trigger event are disclosed. A method includes executing a transaction on a table comprising database data, wherein executing the transaction comprises generating a new table version. The method includes, in response to the transaction being fully executed, generating a change tracking entry comprising an indication of one or more modifications made to the table by the transaction and storing the change tracking entry in a change tracking stream. The method includes executing a task on the new table version in response to a trigger event.
