Synchronous activity execution without task queue

akrjohn · July 21, 2022, 5:00pm

Hi Team – I have a requirement to execute all steps synchronously.
Can this be done without going via a task queue ?
In this case, i have to execute let’s say 5 activities and respond in 2 seconds with the results.

What is the best way to achieve this.

Regards,

John

You can use local activities for that purpose.
Which SDK?

I am using Java SDK.
Is there some sample that i can look at?
