Abstract: Burst performance of a database query may be determined according to a size of the database query. A query to a database may be received. A size may be determined for the query. If the size is less than a size threshold assigned to a first query engine, then the query may be performed at the first query engine. If the size is greater than or equal to the size threshold assigned to the first query engine, then the query may be performed at a second query engine.

Abstract: A centralized data store may provide multiple processing environments access to data. Different data processing clients may determine structural data for a data set stored in a remote data store. An access coordination scheme may be implemented to grant permission to the different processing clients to perform various operations with respect to the portions of the data set. The data processing clients may then access the data set according to the structural data so that operations may be performed with respect to the data permitted by the access coordination scheme to the data processing clients.

Abstract: A data store may implement dynamically assign storage locations to logical partitions according to query predicate indexes. Query predicate indexes may be maintained for individual storage locations in a data store that indicate whether storage locations store data values that do not satisfy a query predicate. The query predicate indexes may be evaluated to assign the storage locations to one or multiple logical partitions. The logical partitions may then be utilized to provide access to data stored in the data store. In some embodiments, a logical partition may be a remote storage partition that identifies data in storage locations to copy to a remote data store.

Abstract: The configuration of computing resources for executing queries may be selected. A comparison of the configuration of computing resources that executed previous queries may be made to select the configuration of computing resources for a received query. A historical query execution model maybe applied, in some embodiments, to determine a resource configuration for computing resources to execute a query. The computing resources may be selected from available computing resources according to the determined resource configuration.
