v1.1.0-alpha2

See Azure Blog post for more details on this release.

• Singleton
  • New SingletonAttribute for job functions that allows you to declaratively specify that only a single instance of the function should be run at any given time (even across scaled out instances).
  • Behind the scenes, this distributed locking is achieved by using Blob leases.
  • Singleton locking can be based on a custom scopes, which can come from path binding (i.e. from trigger data)
  • Support for Singleton Listeners (i.e. a trigger binding can declare its listener Singleton). An example of this is TimerTrigger. For a timer, you don't want it running the same schedule on multiple scaled out instances.
  • Sample here
• Logging/Tracing Extensibility
  • Allow custom TraceWriters to be plugged into the host via JobHostConfiguration.Tracing
  • Allow the Console output TraceLevel to be customized via JobHostConfiguration.Tracing.ConsoleLevel. This is very useful (and recommended) for local debugging.
  • Added a new TraceWriter binding (similar to TextWriter) that allows functions to bind to the TraceWriter
  • Sample here
• ServiceBus Messaging improvements
  • Allow deep customization of Message processing via ServiceBusConfiguration.MessagingProvider
  • MessagingProvider supports customization of the ServiceBus MessagingFactory and NamespaceManager
  • A new MessageProcessor strategy pattern allows you to specify a processor per queue/topic
  • Support message processing concurrency by default (previously there was no concurrency)
  • Easy customization of OnMessageOptions via ServiceBusConfiguration.MessageOptions
  • Sample here
• Lowered the JobHostQueuesConfiguration.MaxPollingInterval to 100ms (from 2 seconds)
• Fixed bugs in Blob container scan logic
• Misc. bug fixes
