Publishing between Map Image vs Feature Layer

[cardiokan]

HI all,

As it has been mentioned many times, grouping is not a option with feature layers.

I have noticed grouping works if you publish with map image layer type. Can anyone tell me the main difference and if i was to publish all my layers as map image instead of feature layers, what issues could occur?

@Anonymous User Just another question, you mentioned offline cache. How does map image service work on a mobile device if for example it had to be cached?

You can absolutely take map services offline. The export operation on the map service allows users to create offline packages containing the cached service, so long as the necessary properties are set. For more information on this process, see: https://enterprise.arcgis.com/en/portal/latest/use/take-maps-offline.htm

Thanks - Calvin from your experience is feature layers more widely used or map services?

I am struggling to see benefits of feature layers apart from editing functionality.
