Abstract: A database management system receives a command defining a view of the database. The view definition is accepted without determining whether references to schema elements within the view definition are resolvable to existing elements of the database schema. A query of the view is received. In response to the query of the view, the database management system resolves references to schema elements in the view definition by determining whether the references correspond to data available for processing the query.

Abstract: Database queries may be performed using resources based on a determined size of the database query. Database query size may be dynamically determined for a database query when the query is received. The database query may be assigned to resources used for database queries of the determined size. In some embodiments, timeouts may be applied to reassign database queries to different resources if the performance of the database query exceeds a timeout threshold.

Abstract: A computer system comprises memory to store computer-executable instructions. The computer system may, as a result of execution of the instructions by one or more processors, cause the system to load a first subset of a set of data elements into a first cache, load a second subset of the set of data elements into a second cache, and as a result of elements of the first subset being processed, issue commands to place elements of the second subset into the first cache to enable processing the second subset to be processed from the first cache.
