Abstract: A system and method of scaling capacity of data warehouses to user-defined levels. The method includes provisioning a data warehouse including a plurality of processing resources, the plurality of processing resources including at least one processor and at least one storage device. The method includes receiving a request to process database data stored on a storage platform including a plurality of shared storage devices in association with the data warehouse, wherein the request indicates a performance level for processing the request. The method includes determining that a capacity of the plurality of processing resources of the data warehouse would reach a threshold capacity when processing the request according to the performance level. The method includes increasing the capacity of the data warehouse for the data warehouse to process the request according to the performance level.

Abstract: Providing access to consumer information on a private data exchange is described. In an example, privileges are assigned to a share object, granting access to consumer information obtained from a query against data referenced by a data listing of a data exchange. The data exchange comprises one or more data listings provided by one or more data providers. In response to the share object being added to a list of consumed share objects of a data provider that provided the data listing, a database is generated that references the consumer information based on the share object. Access to the database is granted to the data provider that provided the data listing.

Abstract: Disclosed herein are embodiments of systems and methods for partition-based scanning of external tables for query processing. In an example embodiment, a database platform receives a query that includes one or more predicates, where the query is directed at least to data in an external table that is stored in an external storage platform that is external to the database platform. The database platform identifies, based on metadata that summarizes the data in the external table, one or more partitions of the external table that potentially include data that satisfies the one or more predicates. The database platform also identifies, from the one or more identified partitions, data that satisfies the one or more predicates. The database platform sends a response to the query to the client, the response comprising the data satisfying the one or more predicates.

Abstract: Techniques for configuring managed event tables include generating at a first process of an execution node, log data associated with execution of user-defined function (UDF) code. The log data is provided from the first process to a second process of the execution node. The first process is configured as a sub-process of the second process. The log data is formatted using the second process of the execution node, to generate formatted log data. The formatting is based on a configuration of a managed event table that is external to the execution node. The formatted log data is communicated from the second process of the execution node into a managed event table maintained at a computing node that is external to the execution node.

Abstract: Techniques for database configurations for remote deployments include a method performed by a data platform executing instructions on at least one processor. The method includes provisioning by at least one hardware processor, a remote deployment of a data platform with a plurality of objects. The plurality of objects includes at least one task object associated with a primary deployment of the data platform. The method further includes detecting using the at least one task object of the plurality of objects, a request to replicate a database stored at the primary deployment of the data platform at the remote deployment. Responsive to the request, database data is pushed from the database stored at the primary deployment to at least a second object of the plurality of objects provisioned at the remote deployment.

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.

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: 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: Systems, methods, and devices for generating a transactional change tracking summary for a database. A method includes executing a transaction on a table of a database, wherein the table includes a micro-partition and the transaction is executed on the micro-partition. The method includes, in response to the transaction being fully executed, generating a change tracking entry comprising an indication of one or modifications made to the table by the transaction. The method includes storing the change tracking entry in a change tracking stream, wherein the change tracking stream includes one or more sequential change tracking entries that each correspond to a different transaction that is fully executed on the table.
