The <info>%command.name%</info> command consumes messages and dispatches them to the message bus.

    <info>php %command.full_name% <receiver-name></info>

To receive from multiple transports, pass each name:

    <info>php %command.full_name% receiver1 receiver2</info>

Use the --limit option to limit the number of messages received:

    <info>php %command.full_name% <receiver-name> --limit=10</info>

Use the --failure-limit option to stop the worker when the given number of failed messages is reached:

    <info>php %command.full_name% <receiver-name> --failure-limit=2</info>

Use the --memory-limit option to stop the worker if it exceeds a given memory usage limit. You can use shorthand byte values [K, M or G]:

    <info>php %command.full_name% <receiver-name> --memory-limit=128M</info>

Use the --time-limit option to stop the worker when the given time limit (in seconds) is reached.
If a message is being handled, the worker will stop after the processing is finished:

    <info>php %command.full_name% <receiver-name> --time-limit=3600</info>

Use the --bus option to specify the message bus to dispatch received messages
to instead of trying to determine it automatically. This is required if the
messages didn't originate from Messenger:

    <info>php %command.full_name% <receiver-name> --bus=event_bus</info>

Use the --queues option to limit a receiver to only certain queues (only supported by some receivers):

    <info>php %command.full_name% <receiver-name> --queues=fasttrack</info>

Use the --no-reset option to prevent services resetting after each message (may lead to leaking services' state between messages):

    <info>php %command.full_name% <receiver-name> --no-reset</info>
EOF
