Create View Layer slow / unresponsive for layer with many features

[DataOfficer]

We have noticed that when trying to create a view layer from a hosted feature service containing many features (~700,000), the page becomes very slow and often completely unresponsive. Has anyone else experienced the same or come up with a solution?

Hi there,

A few questions to help us diagnose this..

• Is the behavior consistent? Are there times it works and other time it does not?
• Is it always the same dataset or varying services that see this behavior?
• Do these services in question have a large schema (i.e. a lot of fields)? Attachments?

Thanks!

Hi @sarah_maisel ,

In answer to your questions:

- yes the behaviour appears to be consistent, and has been experienced by multiple users

- so far this appears related to one hosted feature layer (described below)

- the service contains ~700,000 features, contains 3 sublayers and a related table, the sublayers have anywhere between 69 and 187 fields, and the feature service does have attachments.

Thanks

Hi @sarah_maisel , did you see my response above?
Many thanks,

Hi 

Were you able to resolve this issue?  We're having similar problems - and our layer has about 400K records less than yours....

Thanks

The performance of this has certainly improved (for us at least) since I originally posted this. One thing that helped on occasion when we were having issues was to zoom the map in the right-hand pane in to a small area so that it wasn't trying to symbolise lots of features. However I still find the view layer creation process to be a bit buggy and unreliable.
