Clock-driven scheduling
Webjobs is called the clock-driven or time-driven approach because each scheduling decision is made at a specific time, independent of events, such as job releases and completions, … WebClock-Driven (Time-Driven) -- Overview Scheduling decision time: point in time when scheduler decides which job to execute next. Scheduling decision time in clock-driven schedulers is defined a priori. For example: Scheduler periodically wakes up and generates a portion of the schedule.
