What is asynchronous and synchronous process?
A synchronous process is a process that can be executed without interruption from start to finish. However, the user must wait for the process to complete. An asynchronous process is a process that the Workflow Engine cannot complete immediately because it contains activities that interrupt the flow.
What is an asynchronous event?
An asynchronous event is an event that runs outside the application’s main thread. The best way to understand is to compare to events that run synchronously. The most typical example would be loading a web page.
What is the difference between a synchronous event and asynchronous event give example?
An asynchronous event occurs after an action has taken place, and a synchronous event occurs before an action has take place. For example, an asynchronous event is ItemAdded, and its sister synchronous event is ItemAdding. Synchronous events are often referred to as Before events.
How is a synchronous process different from an asynchronous process?
With a synchronous process, you can immediately check for process results that were written to item attributes or directly to the database. However, the user must wait for the process to complete. An asynchronous process is a process that the Workflow Engine cannot complete immediately because it contains activities that interrupt the flow.
Which is the best definition of asynchronous communication?
File based communication is often considered to be asynchronous. One party writes a file but does not care if the other party is active, fetches the file or is able to process it.
Is there such thing as a forced synchronous process?
Since a forced synchronous process never writes to the database, using a non-unique item key such as #SYNCH is not an issue. Your process definition, however, must adhere to the following set of restrictions: No notification activities are allowed. Limited blocking-type activities are allowed.
When does the workflow engine execute a process synchronously?
The Workflow Engine executes a process synchronously when the process includes activities that can be completed immediately, such as function activities that are not deferred to the background engine. The Workflow Engine does not return control to the calling application that initiated the workflow until it completes the process.
