Messaging

Messaging provides real-time and asynchronous communication capabilities, supporting channels, direct messages, threads, and rich media. It includes message persistence with full CRUD operations, read/delivery receipts, status indicators, and offline caching with optimistic UI updates. The system offers push notifications, search and filtering, and scalable delivery via an event-driven backend (WebSocket/long-polling fallbacks). Security features include end-to-end or at-rest encryption where appropriate, access controls, and moderation support (filters, reporting). APIs and SDKs expose endpoints for sending, retrieving history, updating, deleting, and managing conversations, ensuring seamless integration across clients and platforms.
