    Abstract: A method for directing queries to encrypted database files includes acquiring a mapping that links a first encrypted file with a different encrypted file. The first encrypted file is generated based on a first encryption key. The method includes generating, by one or more processors based on the mapping, an updated mapping to link a second encrypted file with the different encrypted file. The second encrypted file is generated based on a second encryption key. The method includes determining an arrival time of a query. The method includes directing, based on the arrival time, the query to the first encrypted file or the second encrypted file.

    Abstract: A method for a multi-cluster warehouse includes allocating a plurality of compute clusters as part of a virtual warehouse. The compute clusters are used to access and perform queries against one or more databases in one or more cloud storage resources. The method includes providing queries for the virtual warehouse to each of the plurality of compute clusters. Each of the plurality of compute clusters of the virtual warehouse receives a plurality of queries so that the computing load is spread across the different clusters. The method also includes dynamically adding compute clusters to and removing compute clusters from the virtual warehouse as needed based on a workload of the plurality of compute clusters.

    Abstract: A method for a multi-cluster warehouse includes allocating processing units as part of a data warehouse. The processing units access data within one or more databases in cloud storage resources. The method also includes providing one or more queries to each processing unit within the data warehouse. In response to the queries, each processing unit performs database operations on a particular portion of a database table. The method also includes monitoring a workload of the processing units to determine that a processing capacity of the processing units has reached a threshold processing capacity. The method also includes dynamically adding additional processing units to and removing processing units from the data warehouse as needed based on a workload of the processing units.

    Abstract: Systems, methods, and devices for implementing secure views for zero-copy data sharing in a multi-tenant database system are disclosed. A method includes receiving, by a cross-account, a grant to access a share object comprising a secure view and usage functionality associated with a secure user-defined function (UDF) to underlying data. The method includes accessing, by the cross-account, the share object using the grant. The method includes sending a request to a share component to cause the share component to implement the secure view and the usage functionality associated with the secure UDF. The method includes sending a query to the share component to cause the share component to implement the secure UDF.

    Abstract: A method of sharing data in a multi-tenant database includes generating a share object in a first account comprising a share role. The method includes associating one or more access rights with the share role, wherein the one or more access rights indicate which objects in the first account are accessible based on the share object. The method includes granting, to a second account, cross-account access rights to the share role or share object in the first account. The method includes receiving a request from the second account to access data or services of the first account. The method further includes providing a response to the second account based on the data or services of the first account.
