Running the Consumer

A manual queue:consumer:start exits after 5000 messages and dies with your SSH session. Pick one of these three for anything beyond a test.

Option A — Magento cron (simplest)

Magento's consumers_runner cron job starts declared consumers automatically. Check app/etc/env.php:

'cron_consumers_runner' => [
    'cron_run' => true,
    'max_messages' => 1000,
    'consumers' => [],   // empty = run every declared consumer
],

An empty consumers array runs all of them. If yours lists specific consumers, add 'aireview.translation.generate'.

Then make sure Magento cron itself is installed:

php bin/magento cron:install

Best default

If you have no strong reason to do otherwise, use this. It needs no extra process supervision and survives deploys.

Option B — Supervisor (best for busy stores)

[program:aireview_translation]
command=php /var/www/magento/bin/magento queue:consumer:start aireview.translation.generate --max-messages=1000
numprocs=1
autostart=true
autorestart=true
user=www-data
stdout_logfile=/var/log/supervisor/aireview_translation.log
stderr_logfile=/var/log/supervisor/aireview_translation_error.log

supervisorctl reread && supervisorctl update

Option C — systemd

[Unit]

After=network.target mysql.service

[Service]

ExecStart=/usr/bin/php bin/magento queue:consumer:start aireview.translation.generate --max-messages=1000
Restart=always
RestartSec=5

[Install]
WantedBy=multi-user.target

systemctl daemon-reload
systemctl enable --now aireview-translation

Keep it to one process

More consumers will not make it faster

Translation is an outbound API call, not CPU-bound work. Parallel consumers mostly buy you provider rate-limit errors. Start with numprocs=1 and only add more if you have confirmed your provider's limits allow it.

Restart after configuration changes

The consumer caches configuration at start. After changing the provider, key, or model, restart it:

supervisorctl restart aireview_translation     # or
systemctl restart aireview-translation
