Further down in the chapter on scheduler there are these paragraphs. Once a task exists (there is a record in the "scheduler_talk" table), is QUEUED, and is ready (*mmeets* all the conditions specified in the record) it can be picked up by a worker. As soon as a worker is available it picks the first ready task schduled to run. The worker *create(s)* an entry in a another table" "scheduler_run" (also create*(d)* by the scheduler).
The table "scheduler_run" stores the status of all running tasks. Each record references a task that has been picked up by a worker. *Once* task can have muliple runs. For example *on/a *task scheduled to repeat 10 times at 1h *distance/intervals?*, will probably have 10 runs (unless one *failes*or they take longer than 1h). <
