    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: 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: A system and method for pruning data based on metadata. The method may include receiving a query that includes a plurality of predicates and identifying one or more applicable files including database data satisfying at least one of the plurality of predicates. The identifying the one or more applicable files including reading metadata stored in a metadata store that is separate from the database data. The method further includes pruning inapplicable files including database data that does not satisfy at least one of the plurality of predicates to create a reduced set of files and reading the reduced set of files to execute the query.

    Abstract: A system and method for pruning data based on metadata. The method may include receiving a query comprising a plurality of predicates and identifying one or more applicable files comprising database data satisfying at least one of the plurality of predicates. The identifying the one or more applicable files including reading metadata stored in a metadata store that is separate from the database data. The method further includes pruning inapplicable files comprising database data that does not satisfy at least one of the plurality of predicates to create a reduced set of files and reading the reduced set of files to execute the query.
