# systemd unit — PlytixMage FastAPI (uvicorn multi-worker, enqueue-only)
#
# Goal: keep HTTP responsive. Long Magento/channel/taxonomy/readiness jobs
# must stay in their dedicated worker units (do NOT enable embedded workers here).
#
# Install:
#   sudo cp scripts/systemd/plytixmage-api.service /etc/systemd/system/
#   sudo systemctl daemon-reload
#   sudo systemctl enable --now plytixmage-api.service
#   journalctl -u plytixmage-api.service -f
#
# Edit User / WorkingDirectory / EnvironmentFile / paths to match the server.
#
# Companion workers (already running as separate units):
#   python magento_worker.py                          # x4
#   python -m app.jobs.channel_job_worker
#   python -m app.jobs.master_taxonomy_job_worker
#   python -m app.jobs.refresh_channel_readiness --poll 60
