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:
1 bin/magento queue:consumers:start [--max-messages=<value>] [--batch-size=<value>] [--single-thread] [--area-code=<value>] [--multi-process=<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:
1 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.
--multi-process option is present in the
queue:consumers:start command, but to run consumers with parallel processes, configure the
multiple_processes option in
/app/etc/env.php. Otherwise, if
queue:consumers:start is called with the
--multi-process option, it will only work on a single thread.
