You are tasked with implementing a RESTful API for a real-time messaging platform. How would you handle CRUD operations to ensure data consistency and real-time updates?

  • Use a message broker like RabbitMQ or Kafka for real-time updates.
  • Implement optimistic locking to handle concurrent updates.
  • Utilize WebSockets to enable real-time communication between clients.
  • Use RESTful long polling to provide real-time updates.
Implementing CRUD operations for a real-time messaging platform requires ensuring data consistency and real-time updates. Option 1, "Use a message broker like RabbitMQ or Kafka for real-time updates," is a common approach. Message brokers enable real-time communication between clients and ensure data consistency by broadcasting messages to subscribers. While other options (optimistic locking, WebSockets, and long polling) can play a role, a message broker is a foundational component for real-time messaging systems.
