When does it make sense to use pulldata as opposed to lists in the Choices tab - is a list of ten thousand records acceptable for pulldata?
pulldata doesn't create list choices - it looks up data based on a previous entry. External Choice lists does offload the choices from eh choices worksheet (Cascading and external selects—Survey123 for ArcGIS | ArcGIS ). Yes, I would say once the list becomes more than a few hundred the external select should be used instead.
Thanks @James Tedrick. I figured out how the choice filter will be a workaround for my original plan to use external data. The search () feature would really be valuable with dynamic lists. During testing I also realized that multiple CSVs can be used with a survey. I see this very valuable too. But then at what point will the survey be efficient in terms of file sizes and publishing. I see the importance of load time but it would nice to also see the file size and the size threshold - which could be different based on network speed.
