Composite Transactions for SOA 写道
A transaction is defined as a task that is composed of one or more operations or related interactions that may need to be cancelled or “rolled back” after the point of execution.
A long running transaction is a transaction where the total duration exceeds the duration of an individual interaction by many orders of magnitude. In this situation, the cancellation of an individual interaction within a long transaction may occur long after the interaction has been executed.
