Library provides middleware that gives you ability to execute commands via Tactician in async or delayed way.

Configuration

Before usage, please documentation for lamoda/queue-bundle

Bundle provides special middleware for tactician integration. This middleware add supports of async command execution, event with scheduling.

To enable this feature do the following:

  1. Add extra configuration:
    lamoda_tactician_queue:
        tactician_id: tactician.commandbus # Command bus service id
    
  2. Add at least one strategy, that will convert commands into jobs:
    services:
        # ...
        several_domain_commands_strategy:
            class: Lamoda\TacticianQueue\Middleware\QueueProducerStrategy\CommandsListToCommandJobStrategy
            arguments:
                - async_command_queue
                - async_command_exchange
                - [ My\AsyncCommandInterface, My\SecondCommand ]
                - 15 # optional delay
            tags:
                - { name: tactician_queue.job_producing_strategy }
  3. Add queue middleware to the list of tactician middlewares:
    tactician:
        commandbus:
            default:
                middleware:
                    - tactician.middleware.locking
                    - lamoda_tactician_queue.middleware # Here it is
                    - tactician.middleware.command_handler
  4. Now every time you call
    <?php
    $commandBus->handle(new My\SecondCommand());
    this command will be published into the queue.
