Lamoda Tactician Queue Middleware

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

Installation

composer require lamoda/tactician-queue

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.
