What Is a Slot?


A demo slot is an area that can be used to meet a specific need or purpose. In hockey, the slot is the area between the two face-off circles in the offensive zone. It can also be used in scheduling, BigQuery, and air traffic management. In these industries, the use of a slot helps to promote open communication between departments and teams.

The slot is an area of the rink in which players can shoot a puck. It represents the area of the ice with the best chances of scoring a goal without a deflection. Its low location allows players to take wrist shots with a clear line to the goal. On the other hand, defenders will set up the slot as a no-man’s-land.

The slot is also called the “sweet spot,” as it is the area between the hash marks. When a player gets open in the slot, he or she is called a “slot player.”

In BigQuery, it’s a time-slot

In BigQuery, a time-slot is a block of compute resources that a job can use. It is used to parallelize a query. There are several ways to request slots. Users can purchase slots on an on-demand basis or pay a flat rate for a fixed number of requests. They can also share slots with other projects using BigQuery Reservations. For example, if projectA requests 1,000 slots for a given job, projectB may borrow some slots and be charged the difference. This way, a user can monitor the use of their slots and plan their capacity for their workload.

BigQuery customers have reservations in tens of thousands of slots. Each slot represents half of a CPU core. BigQuery instances can process billions of rows per second and can consume thousands of CPU cores at once.

In air traffic management

Slots are important to the smooth operation of air services at an airport. They ensure that aircraft can land or take off during certain times, and that traffic is sequenced to avoid congestion. The IATA sets worldwide slot management standards in its Worldwide Slot Guidelines (WSG). The WSG is an agreement among IATA Member airlines and airport coordinators. It is considered the industry’s standard methodology. The IATA Standard Schedules Information Manual (SSIM) includes recommended practices and messaging formats for airport slots.

Slots can be divided into two types: time zones and capacity zones. These are the times when the declared capacity level is higher or lower for an airport. Depending on the type of flight, certain airlines prefer specific times. Moreover, certain times of the day are better for business travellers. Therefore, airlines often use time-dependent declared capacity levels, which function as a queuing recovery mechanism.

In scheduling

A network can schedule resources over a period of time called an in scheduling slot. This can be advantageous in many situations, including when users need to access the internet during specific hours of the day. It can also provide a more consistent experience by providing a predictable schedule and reducing the need for rerouting.

A network may use a scheduling block to divide the time available for memory operations. The scheduling block then provides a BWP allocation to each individual vRAP.
