The way you did things in Engage may need to be approached in a different way in Genesys Cloud. What is your use case for needing to retrieve the 20K workitems? If you can let us know the end goal that you are trying to achieve then we can better advise you on an approach to use in Genesys Cloud.

Hi
We are looking into replacing our Genesys Engage environment with Genesys Cloud taskmanagement.
In our current solution, we process about 20'000 workitems per day, with the requirement that single endusers are able to view about 500 workitems (from private or shared work).

So, how could we efficiently retrieve a complete list of workitems in GC taskmanagement?
We tested "/api/v2/taskmanagement/workitems/query/jobs", which implements an async approach which looks inefficient, requiring one query job per page retrieved (max. page size of 200 workitems).

Is the workitems list view from the Genesys Cloud UI using the same approach (per user per request per page one async workitems query job)?

Jobs from "/api/v2/taskmanagement/workitems/query/jobs" are not manageable.
You need to catch the job id right at job creation, to async retrieve job results, and there is no API available to drop those query jobs.
Any problem from this, i.e. will GC manage job cleanups by itself?

Thanks a lot for your advice and have a nice day.
