How to read a file on demand
I have a file stored permanently in a directory.
This file contains a lookup list that the business users can update at any time.
My application needs to read the contents of the file and use them in processing.
How can I read the file only when a at the moment it is needed?
I don't think a File Listener would work because a listeners waits for a certain file to arrive and then processes it as soon as it finds it.
I need to be able to call 'something' from my activity to read the file only at the needed moment.
Is there any Pega capability to do this? I can't find anything similar on google.

I think you are right. The file listener will always try to read the file. Could you store your file in another directory and move it to File Listener directory when needed?

It sounds like the file contains structured data which could also reside in a data store.
Can the business instead come into App Studio and update this lookup list as Records of a Data Object that are stored in Pega? If kept as a file, you would need to implement some sort of integration and turn that file content into instances of classes anyway, so it would be:
- Less configuration effort and less things-that-can-go-wrong if you don't need to build an integration; and
- Perhaps a better maintenance experience for the business to use a Records editor than updating a file on a shared folder somewhere.
