File consumption order in a file listener
In our application, we have a File Listener on 1 thread with a 60sec polling interval.
Due to the growing number of files that the listener have to process everyday (more than 20 000 new file per day), i want to know in which order PEGA process the files ?
How to be sure to process the most old files first ?
I didn't find any article about that subject.
Thanks.

Thanks for your answer.
It means that in a folder where 2000 or 3000 new files are added per hour, we cannot predict in which order files will be processed.
How increasing polling interval will help in my case ?
We have 3 nodes for application users, and 1 node for this file listener.

We suggest you deploy this File Listener to all 3 nodes for load balancing ( consult with your architects).
Polling interval will give threads processing files some delay.

But if the activity that process each file need to modify a case.
What if in an exceptional case, on multiple node, at the same time we need to modify the same case.
Does PEGA handle that correctly ?

On growing files to be processed, how many nodes you have in system? I suggest you increase polling interval.
