Base64 Images and SQL - Slow Transfer Speeds and Inconsistent Collects

(0) ShareShare
ReportReport
Posted on by 30

Hi,

 

We've currently got an app which is designed to work offline and then collect the contents of a form back to SQL. Each form normally has about 10-15 images, which we are currently converting to base64. 

We originally had on premise SQl to store the images but found this could take 10-20 minutes to transfer that amount of images in base64. We then switched to Azure SQL< which brought to speed down to about 3-4 minutes, however our new problem which this is that it can be hit and miss on wether it finishes the collect. We've had to introduce a follow up check after each time the app collects its contents back to Azure to understand if all of the images have made it.

 

Basically, neither route is ideal between slow speeds and inconsistent transfers of data. Is this normal across other users following a similar process and if not, is there a better way of doing this which is faster and more reliable?

    Hi @Arrow3009 ,

     

    I suggest that you could use Concurrent function in canvas app. This function can do multiple operations at the same time.

    In addition, you could use canvas to call flow and use flow to add rows in your datasource.
