Important: #103140 - Allow to configure rate limiters in Message consumer (Symfony Messenger)

See forge#103140

Description

This change introduces missing configuration options for Symfony Messenger-based rate limiters.

A rate limiter controls how frequently a specific event (e.g., HTTP request or login attempt) is allowed to occur. It acts as a safeguard to prevent services from being overwhelmed — either accidentally or intentionally — thus helping to maintain their availability.

Rate limiters are also useful for controlling internal or outbound processes, such as limiting the simultaneous processing of messages.

More information about the rate limiter is available in the Symfony Rate Limiter component documentation.

Usage

Configure a rate limiter per queue

Rate limiters can be defined in your service configuration EXT:yourext/Configuration/Services.yaml. The name specified in the settings is resolved to a service tagged with messenger.rate_limiter and the corresponding identifier.

Example Configuration:

EXT:yourext/Configuration/Services.yaml 
messenger.rate_limiter.demo:
  class: 'Symfony\Component\RateLimiter\RateLimiterFactory'
  arguments:
    $config:
      id: 'demo'
      policy: 'sliding_window'
      limit: '100'
      interval: '60 seconds'
    $storage: '@Symfony\Component\RateLimiter\Storage\InMemoryStorage'
  tags:
    - name: 'messenger.rate_limiter'
      identifier: 'demo'

messenger.rate_limiter.default:
  class: 'Symfony\Component\RateLimiter\RateLimiterFactory'
  arguments:
    $config:
      id: 'default'
      policy: 'sliding_window'
      limit: '100'
      interval: '60 seconds'
    $storage: '@Symfony\Component\RateLimiter\Storage\InMemoryStorage'
  tags:
    - name: 'messenger.rate_limiter'
      identifier: 'default'
