Sync in write to records

No. You somehow need to tell the user interface when to refresh the data from the backend. This can be a single node or multiple nodes down into the process.

Do you have a specific reason to look for an alternative option?

Hi Stefan, Thanks for your reply.

Based on my understanding enable activity will reduce the application performance.

Chaining make the Appian process execution engines execute the nodes in the chain be executed with the highest priority. That's all. Now when you enable chaining on all nodes in all processes, you will end up with a confused process scheduler.

So, does chaining reduce app performance? No, but using it too much will have negative effects on the system.

In the end, it is pretty simple. Do not enable chaining except for the following use cases:

- Control refresh behaviour of an interface

- Control return timing of a process started by a!startProcess

- Guide a user seamlessly through multiple user input tasks in a process

And keep these chains as short as possible!

I have below question: -

1. What does it mean if we activity chain two user input task? - We all know it retains the assignee.
   
   
2. What does it mean if we activity chain two script task? - As per you explained above, what if we have below scenario.
   • Two parallel paths (Path P1 and P2 running in parallel).
     Path P1 have two script tasks (ST1 and ST2 with activity chained) and
     Path P2 have two script tasks (ST1 and ST2 without activity chained)
     
     How does Appian prioritize, what does it actually mean?

1) True

2) Parallel flows do not define any kind of priority. When chained, Appian will just try to execute the chained nodes as fast as possible. Non-chained nodes are delayed.

Gotcha. Thanks
