afr do not use schedulers. Only unify uses them to schedule nodes for file
creation. You might be interested in "read-node" and "read-schedule" options
of afr.

A centipede was happy quite, until a toad in fun,
Said, "Prey, which leg comes after which?",
This raised his doubts to such a pitch,
He fell flat into the ditch,
Not knowing how to run.
