#
# rc.d script for the vrobbler background Celery worker.
#
# PROVIDE: vrobbler_celery_background
# REQUIRE: NETWORKING postgresql redis
# KEYWORD: shutdown
#
# Installation (on the FreeBSD jail):
#
#   install -m 0555 rc.d/vrobbler_celery_background /usr/local/etc/rc.d/vrobbler_celery_background
#   sysrc vrobbler_celery_background_enable="YES"
#   service vrobbler_celery_background start
#
# Configuration (via sysrc or /etc/rc.conf):
#
#   vrobbler_celery_background_queues  - queues to consume  (default: background)
#   vrobbler_celery_background_bin     - path to celery     (default: /usr/local/bin/celery)
#   vrobbler_celery_background_flags   - extra daemon(8) flags
#
# Consumes the "background" queue where heavy, scheduled off-peak jobs are
# routed (database backups, trend computation, sentiment backfill, chart
# rebuilds, historical imports). Low concurrency keeps these CPU/I/O heavy jobs
# from starving the other workers. The nodename is fixed to
# background@<hostname> so it can coexist with the other workers on one host.
