Start message queue consumers

In addition to the command arguments described in this topic, see Common arguments.

Run all Magento CLI commands as the Magento file system owner.

You must start a message queue consumer to enable asynchronous operations such as Inventory Management mass actions and REST bulk and asynchronous endpoints. To enable B2B functionality, you must start multiple consumers. Third-party modules might also require that you start a custom consumer.

Start message queue consumers

To start message queue consumers:

bin/magento queue:consumers:start [--max-messages=<value>] [--batch-size=<value>] [--single-thread] [--area-code=<value>] <consumer_name>

After consuming all available messages, the command terminates. You can run the command again manually or with a cron job. You can also run multiple instances of the magento queue:consumers:start command to process large message queues. For example, you can append & to the command to run it in the background, return to a prompt, and continue running commands:

bin/magento queue:consumers:start <consumer_name> &

See queue:consumers:start in the Magento command-line reference for details about the command options, parameters, and values.
