Pulldata @layer slow load

MattVizard — Fri, 10 May 2024 05:41:14 GMT

I'm using the pulldata(@layer) function to pull 45 pieces of data into a survey123 form based on a field entry in the form. This has slowed down the survey load time considerably and slowed down the drop down list load time.

Is there a way to stop calculations until a certain condition is met. Or is there a more efficient way to pull data points form the feature layer?

make the question relevant so it only calculates when the condition is met.

Use the once() function so that it only calculates once.

Use calculationMode=whenEmpty so it calculates only if empty.

I'd also suggest reducing the 45 pieces. You could:

Make one request, once, then parse the data in the form
Use other ways of interacting with the data - e.g.
- post - webhooks, python snippets
- before - Inbox/edit workflows, custom URL schemes to pass data
User forms and arcade expressions within Field Maps
revisit the workflow method entirely

We use @ChristopherCounsell 's first suggestion. If we have a layer that we want to pull multiple attributes from (often it's pulling parcel ownership and site address), we use a single request and store the results as a hidden text field in the form.

For the individual questions, we use pulldata("@json", ${hidden_json_field}, ...) to access attributes.
