AMQP Feature | Comments |
TCP and TLS transport | Alternative support only, not negotiated TLS |
Transactional publishing to topics and queues | Restricted only to local transactions because Universal Messaging does not support distributed transaction coordinators. |
New Universal Messaging protocol layer threading module | AMQP performance and stability improvements |
Plain and SASL authentication | SASL mechanisms are limited to the ones provided by the underlying JVM. |
Non-transactional publishing to topics and queues | |
Synchronous and asynchronous subscription to topics and queues | |
Durable subscribers | Not all durable types. |
Interoperability with Universal Messaging publishers and subscribers using any of the available client APIs | Requires complete transformation (needs protobuf support). |
Temporary topics and queues | Only session lifetime policy. |
Connection keep alives | |
Credit-based flow control | Credit values < 100 cannot be reliably enforced |
Interoperability with existing AMQP JMS clients (SwiftMQ, Apache QPID) | |
Event transformation API | Reduces marshalling on pure AMQP deployments, allows custom mapping definitions against the default AMQP message format. |
