备注
A work item consists of notifications within a single batch that will be delivered through the same delivery channel. Notification Services divides notification batches into work items to take advantage of batch processing and to deliver notifications via multiple delivery channels in parallel.
When a distributor thread is free, it picks up an available work item to format and deliver. The WorkItemTimeout value configures a time limit for formatting and delivery of the notifications in that work item. If the distributor exceeds the timeout, it returns the work item to the pool of available work items so it can be processed by another distributor thread, assuming there is a retry schedule.
The format of the XML duration data type is PnYnMnDTnHnMnS. For more information about XML data types, see Primitive XML Data Types in the MSDN Library.
