This section covers internals and production-grade operating patterns.

Topics

• Structure of a Message: command/subscription/stream message fields and semantics.
• Queues – internals & delivery tuning: lifecycle configuration, leases, retries, DLQs.
• Delivery semantics and reliability: at-most-once vs at-least-once and idempotency patterns.
• AI Protocol: envelope/frame contract for agent streaming, telemetry, and nested flows.
• AI Knowledge & RAG: deep dive into vector stores, document adapters, and multi-tenant scoping.
• Custom AI Stores: building custom conversation memory and knowledge adapters.
• Standard AI Protocols (MCP & A2A): interoperability via Model Context Protocol and Agent2Agent.
• JavaScript Events: integrating framework events with native JS events.

When to read this section

• you debug cross-service routing and message metadata
• you define production delivery/retry expectations
• you need stronger observability and operational safety controls
• you build custom storage adapters for AI memory or knowledge
• you need deep interoperability with standard AI protocols
