%description
Jobs is a job scheduler for load regulation of Erlang applications. It provides a
queueing framework where each queue can be configured for throughput rate, credit
pool and feedback compensation. Queues can be added and modified at runtime, and
customizable "samplers" propagate load status across all nodes in the system.
Specifically, jobs provides three features:
  - Job scheduling: A job is scheduled according to certain constraints. For
    instance, you may want to define that no more than 9 jobs of a certain type
    can execute simultaneously and the maximal rate at which you can start such
    jobs are 300 per second.
  - Job queueing: When load is higher than the scheduling limits additional jobs
    are queued by the system to be run later when load clears. Certain rules
    govern queues: are they dequeued in FIFO or LIFO order? How many jobs can the
    queue take before it is full? Is there a deadline after which jobs should be
    rejected. When we hit the queue limits we reject the job. This provides a
    feedback mechanism on the client of the queue so you can take action.
  - Sampling and dampening: Periodic samples of the Erlang VM can provide
    information about the health of the system in general. If we have high CPU
    load or high memory usage, we apply dampening to the scheduling rules: we may
    lower the concurrency count or the rate at which we execute jobs. When the
    health problem clears, we remove the dampener and run at full speed again.
