One or more approximations of query output in a data analytics platform are controlled. The one or more approximations are controlled by generating values of error metrics associated with placements of samplers in one or more query execution plans associated with the query, and injecting a plurality of samplers into the query execution plans, using the determined values of the error metrics, in lieu of storing samples of input to the query prior to execution of the query.

Controlling approximations of queries

A virtual network virtual machine may be implemented on a cloud computing facility to control communication among virtual machines executing applications and virtual machines executing middlebox functions. This virtual network virtual machine may provide for automatic scaling of middleboxes according to a heuristic algorithm that monitors the effectiveness of each middlebox on the network performance as application virtual machines are scaled. The virtual machine virtual network may also locate virtual machines in actual hardware to further optimize performance.
