performance decrease in case of activity chaining

Question

Activity chaining is used to show forms in succession , then how activity chaining can decrease the performance .

Konduru Chaitanya · Accepted Answer

When you are using activity chaining the chained nodes would run with first priority. If unnecessary activity chaining is done then this would impact the process execution engines if multiple instances are being triggered or often launched. Unless until you have a huge number of nodes and too many subprocess nodes in your model, I don't think you should be worried about it.

Activity chaining holds resources for the entire chain, even for slow activities. Removing chaining lets Appian free up resources sooner and potentially run things more concurrently, improving performance. Workarounds like simple forms and asynchronous execution are still important for optimal speed. I hope that answers your doubt.

It totally depends usage of chaining. Think of it like waiting in line, if some activities involve complex calculations, database interactions, or there are just too many forms in a row, users might experience delays. This is because Appian holds onto resources for the entire chain, similar to how a long line at a store can slow down everyone. To avoid this, keep your activity chains short and simple, and consider using asynchronous execution (working on tasks in the background) for resource-intensive activities.
