Qpid implements the AMQP protocol. It has a Java and C++ broker, and clients so far for Java (JMS), C++, Python, Ruby, with C# expected soon.
The Java implementation currently supports the following features:
- Most features required by the JMS 1.1 specification. See our roadmap for details of missing JMS features and when we expect to add them.
- Transaction support
- Persistence using a pluggable layer
- Pluggable security using SASL. Any Java SASL provider should be capable of working with Qpid.
- Management using JMX and MC4J (again see our roadmap for details of this feature and our future plans in this area)
- Clustering for scalability
- High performance header-based routing for messages
- .NET API implementation (currently an alpha release; see our roadmap)
