What is a Slot?

A narrow opening or groove, especially one in a door or wall. A gap between a main and an auxiliary airfoil to provide space for airflow and facilitate the smooth passage of air over the wing. An assigned place in a sequence or schedule. The program received a new time slot on the broadcasting schedule. The job was allocated a new slot in the management training program.

In a cable street-railroad track, a narrow continuous opening in the rails through which a grip on the car passes to connect with the traveling cable. In coal mining, a gap between the head of a coal plow and the adjacent face to permit access to cutting heads. In aviation, the gap between a primary and an auxiliary airfoil to allow air to enter the auxiliary wing to reduce drag and help maintain lift. In sports, an unmarked area in front of the goal between the face-off circles on an ice hockey rink.

From Middle English, from Middle Low German, from Proto-West Germanic *sluta (“bolt, lock”), related to the verb sleutana (“to lock”). Cognate with Dutch slot and German Schloss.

The table has a unique form with soft round shapes that contrast with the more masculine steel frames in our collection. It is a beautiful piece that can be used in many different environments and looks great with other materials.

The t-slot table is designed to be mounted directly on the base of the universal testing system, providing an extended work area for the tensile, compression and flexural tests. It features t-slots that run front-to-back, side-to-side and diagonally. This makes it easy to secure components and structures for these tests without the need to remove them from the frame.

The BigQuery scheduler provides eventual fair scheduling for jobs running in a reservation. This means that some queries might experience short periods of getting a disproportionate share of slots compared to others, but the scheduler will correct this in the long run. The scheduler tries to balance being too aggressive in evicting running jobs (which leads to wasted slot capacity) and being too lenient (which leads to longer wait times for other jobs). The result is a dynamic resource allocation algorithm that is constantly reevaluating your query’s current demand and the availability of its slot capacity, ensuring that the dynamic DAG always gives each job its fair share of slots. For more information, see the documentation on the scheduler.
