Description

Currently, GoFr provides excellent support for Redis. However, unfortunately doesn't have Redis Pub Sub support, which is essential for building event-driven architectures and real-time applications.

Adding Redis Pub/Sub native support would enable GoFr applications to easily implement asynchronous messaging without requiring additional message brokers.

Proposed Solution

• Add built-in Redis Pub/Sub client integration to GoFr's core:
  • Native publisher interface for sending messages to channels
  • Subscriber interface with goroutine-based message handling
  • Pattern-based subscriptions (e.g., user.*, order.created)
• Integrate with GoFr's existing Redis configuration and connection management
• Provide middleware support for message processing (logging, metrics, error handling)
• Support for message serialization/deserialization (JSON, protobuf, etc.)
• Configuration through environment variables (e.g., REDIS_PUBSUB_ENABLED=true)
• Graceful shutdown handling for active subscriptions

Use Cases

• Real-time notifications: User activity notifications, system alerts, chat applications
• Cache invalidation: Distributed cache invalidation across multiple service instances
• Background job: Job queues for non-critical async tasks

Benefits

• Consistent GoFr experience: Leverages existing Redis connection and follows GoFr patterns
• Performance: Redis Pub/Sub is lightweight and fast for real-time messaging
• Developer productivity: Native integration reduces boilerplate code
• Cost-effective: Utilizes existing Redis infrastructure without additional components
