Scheduled Workflows in Activiti

[shweta_tiwari]

There is an option in activiti to schedule workflows using Timer Start Event .  They allow scheduling at one particular time or based on certain time period.

So in case of workflows that are scheduled to run in specific time intervals , what is the impact on activiti performance if we have many workflows scheduled at specific time interval and they are getting invoked after some time ?

Also if there is a workflow with 3 steps and starttimer is set to be invoked every 5 minutes.

start–>starttimer –> task1 –> task2–> end

Then, does that mean that this workflow will run in every 5 mins and perform Task1 and Task2?

Hi

time period.

Yes http://www.activiti.org/userguide/#bpmnTimerStartEvent

Then, does that mean that this workflow will run in every 5 mins and perform Task1 and Task2?

Use just one start event (TimerStartEvent). Current DefaultJobExecutor implementation does not guarantee that it will start process on exact time.

Thanks Martin for your comments.  When start timer is called it invokes the workflow but if we want to call our custom implementation while starting a workflow via Job executor is there any way to do that?

what do you mean with 'custom implementation'? You custom java service tasks? If so, that just works.
