DESCRIPTION

Minion::Command::minion::worker starts a Minion worker. You can have as many workers as you like.

WORKER SIGNALS

The Minion::Command::minion::worker process can be controlled at runtime with the following signals.

INT, TERM

Stop gracefully after finishing the current jobs.

QUIT

Stop immediately without finishing the current jobs.

JOB SIGNALS

The job processes spawned by the Minion::Command::minion::worker process can be controlled at runtime with the following signals.

INT, TERM

This signal starts out with the operating system default and allows for jobs to install a custom signal handler to stop gracefully.

USR1, USR2

These signals start out being ignored and allow for jobs to install custom signal handlers.

REMOTE CONTROL COMMANDS

The Minion::Command::minion::worker process can be controlled at runtime through Minion::Command::minion::job, from anywhere in the network, by broadcasting the following remote control commands.

jobs

  $ ./myapp.pl minion job -b jobs -a '[10]'
  $ ./myapp.pl minion job -b jobs -a '[10]' 23

Instruct one or more workers to change the number of jobs to perform concurrently. Setting this value to 0 will effectively pause the worker. That means all current jobs will be finished, but no new ones accepted, until the number is increased again.

kill

  $ ./myapp.pl minion job -b kill -a '["INT", 10025]'
  $ ./myapp.pl minion job -b kill -a '["INT", 10025]' 23

Instruct one or more workers to send a signal to a job that is currently being performed. This command will be ignored by workers that do not have a job matching the id. That means it is safe to broadcast this command to all workers.

stop

  $ ./myapp.pl minion job -b stop -a '[10025]'
  $ ./myapp.pl minion job -b stop -a '[10025]' 23

Instruct one or more workers to stop a job that is currently being performed immediately. This command will be ignored by workers that do not have a job matching the id. That means it is safe to broadcast this command to all workers.
