Workflow Timer Job and Nintex WF

Question

Hi,

My question is about the Timer Job "Workflow".

I have some Nintex Workflows which are set to be executed immediatly and I'm aware that all WF (nintex's includes) are pushed into a queue.

My default Workflow Timer Job is set to be executed every 5 min.

Question : Does it mean that my queue will be empty every 5 min so that all my WF are executed ?

I tested on my 3 tier farm, and my nintex WF are executed immediatly and not when the Workflow Timer Job is executed.

Question : What is the link between Workflow Timer Job and the delay of execution of Nintex WF ?

Thanks

Hi, @Kevin Nguyen ,

To say it short , SharePoint attempts to run Workflows synchronously. When the farm is experiencing a heavy load, say, the number of workflows exceeds 15 per content database (it is a default setting which can be tuned), the workflows will be converted to SPWorkItems and queued. This queue is then handled by the Workflow Timer Job, which runs every 5 minutes by default. The workflow Timer Job is ran by SharePoint Timer Service and by default will be triggered every 5 minutes as you mention. It will tries to run the work items later .

The workflow SPTimer job fires to process pending workflow tasks. This 5 minutes interval also represents the granularity of delay timers within your workflow. If a timer is set to delay for one minute, but the interval timer fires only every five minutes, the workflow delays for five minutes, not one minute.

Workflows, by their very nature, do not execute in a nonstop, linear fashion. Instead, they run for a little while, pause, run some more, and then pause again, continuing in this manner until the process is complete.

More detailed information about the process, please refer to this article: https://learn.microsoft.com/en-us/previous-versions/office/developer/sharepoint-services/dd441390(v=office.12)?redirectedfrom=MSDN#WorkflowScalabilityPerformance_HardwareSoftwareConfig

And Nintex workflow is out of the scope of this forum, I am not certain if the mechanism of default workflow can be applied to Nintex ones, still you can take them as a reference.
