Offline Persistency (Personal Experience)

[fmigg]

Hi All, 

I'm new on Power Apps such as MS Tools. We want to show a demo proposal to our faculty in which we will use Power Apps for gather data through surveys. 

One of the things we'd like to add is the offline persistency, so we could go to rural areas where internet signal is low or sometimes inexistent, and when the app detects internet signal the app submit the surveys to a Sharepoint List. 

I've been reading some documentation about offline functionality and I found that quoted: 

"The offline feature area is still under development and is not optimized for every offline scenario today" 

It also says that this function will NOT be suitable to apply it to scenarios of large data, and it examples like saving thousands of rows in a table, or caching large images or videos.

But what about just a few hundreds? 

We don't expect to pass over 300 daily rows at low wifi areas and much less at rural areas with no internet.

I just wanted to see use cases of the community which had face something similar. To see if a some hundred rows is suitable for offline capabilities. 

Thanks and regards,

Hi @fmigg,

Could you describe more clearly about what function do you want to make when you are offline?

If you want to write data offline and load it when you are online, I sugget you try Savedata and loaddata function.

You could save data in a collection and then load it when you are online.

The limit of collection is 2000.

Here's a doc about it for your reference:

Hi @v-yutliu-msft ,

Being more descriptive I want to submit survey to a Sharepoint list using Flows. The persons responsible of using the app and apply survey will be visiting places where internet is not guaranteed.

What I'd like to do is to be able to realize surveys offline, then once I get some internet signal automatically upload the surveys made to the Sharepoint list. 

The doubt I had is the max number of survey that offline capability could resist (suposing that each survey has 50 questions, mostly Choice question). 

I will take a look at the shared link to see if that fits my justification of using Power Apps and Sharepoint...

Thanks a lot!
