A slot is a narrow opening. It is the area between face-off circles in an offensive zone.
Slots are often used in airports to manage air traffic and prevent repeated delays. They also are used by technology companies to ensure that their teams are moving in the right direction toward business objectives.
The BigQuery slot estimator uses historical performance data to help users estimate the number of slots they need for workloads. It then shows the impact of increasing or decreasing the number of slots on job performance.
In addition, BigQuery’s slot recommender can be used to evaluate the cost of a slot’s capacity. When a customer wants to charge for its usage, the slot recommender can create recommendations based on its historical usage. Using this data, the slot estimator helps customers understand how the capacity of a slot affects their on-demand billing.
Professionals can use slots to schedule meetings and consultations. This can improve team communication and motivate teams. They can also use the tool to allocate resources and establish important deadlines.
For example, financial consultants may use scheduling software to organize appointments and set deadlines. Slot-based scheduling can also be used by health care professionals to help staff manage their time. It can be used to set up presentations and evaluation reviews.
Slots can be invoked by any component. However, they follow normal C++ rules when called directly. If you call a slot expecting a signal, it will report a runtime error.
