// Package control controls which resources a query may consume.
//
// The Controller manages the resources available to each query and ensures
// an optimal use of those resources to execute queries in a timely manner.
// The controller also maintains the state of a query as it goes through the
// various stages of execution and is responsible for killing currently
// executing queries when requested by the user.
//
// The Controller manages when a query is executed. This can be based on
// anything within the query's requested resources. For example, a basic
// implementation of the Controller may decide to execute anything with a high
// priority before anything with a low priority. The implementation of the
// Controller will vary and change over time and this package may provide
// multiple implementations for different controller algorithms.
//
// During execution, the Controller manages the resources used by the query and
// provides observabiility into what resources are being used and by which
// queries. The Controller also imposes limitations so a query that uses more
// than its allocated resources or more resources than available on the system
// will be aborted.
