Messaging Protocols Supported by Artemis ActiveMQ

Apache ActiveMQ Artemis supports several messaging protocols, each with unique features and best-use scenarios. Below is a concise overview:

1. AMQP (Advanced Message Queuing Protocol)

• Pros:
  • Open standard, widely adopted
  • Interoperable across vendors and languages
  • Supports advanced messaging features (transactions, security)
• Cons:
  • Slightly more complex to configure
  • May introduce overhead for simple use cases
• Best for:
  • Heterogeneous environments
  • Interoperability with other AMQP-compliant systems

2. MQTT (Message Queuing Telemetry Transport)

• Pros:
  • Lightweight, low bandwidth
  • Ideal for IoT and mobile devices
  • Simple publish/subscribe model
• Cons:
  • Limited advanced features (e.g., transactions)
  • Not as feature-rich as AMQP or Core
• Best for:
  • IoT, telemetry, and mobile messaging
  • Scenarios with constrained networks

3. STOMP (Simple Text Oriented Messaging Protocol)

• Pros:
  • Simple, human-readable text protocol
  • Easy to implement in many languages
• Cons:
  • Lacks advanced features (e.g., transactions, security)
  • Less efficient for high-throughput
• Best for:
  • Simple messaging needs
  • Quick prototyping and debugging

4. OpenWire

• Pros:
  • Native protocol for ActiveMQ "Classic"
  • Good integration with legacy ActiveMQ clients
• Cons:
  • Not an open standard
  • Limited to Java and a few other languages
• Best for:
  • Migrating from ActiveMQ "Classic"
  • Existing OpenWire client applications

5. Core Protocol

• Pros:
  • Native protocol for Artemis
  • Full feature support (transactions, paging, clustering)
  • High performance
• Cons:
  • Artemis-specific (not interoperable with other brokers)
• Best for:
  • Pure Artemis deployments
  • When maximum performance and features are needed
