What's New in the Windows Azure SDK 2.2 Release (October 2013)
The Windows Azure Service Bus October 2013 release introduces a new feature, Partitioned Entities. This release also contains a new version of Microsoft.ServiceBus.dll (version 2.2). You can obtain the new version of the assembly by downloading the latest NuGet package here.
Partitioned Messaging Entities
Windows Azure Service Bus employs multiple message brokers to process messages and multiple messaging stores to store messages. A conventional queue or topic is handled by a single message broker and stored in one messaging store. Service Bus now enables queues or topics to be partitioned across multiple message brokers and messaging stores. This means that the overall throughput of a portioned queue or topic is no longer limited by the performance of a single message broker or messaging store. In addition, a temporary outage of a messaging store does not render a partitioned queue or topic unavailable. Partitioned queues and topics can contain all advanced Service Bus features, such as support for transactions and sessions.
