Filter delegation Azure DataWarehouse

(0) ShareShare
ReportReport
Posted on by maxsnow 33

Hi Guys

 

I have a table in Azure Datawarehouse with ~50k records.

 

In PowerApps I created a collection with filter function

 

FILTER('Table', email = user().email)

It appears that the app brings 500 records in memory and then applies the filter.

It does not do filtering on ADW side.

 

Does it mean PowerApps do not delegate filtering to ADW or I am doing something wrong?

 

Thank you,

Max

    Hi @maxsnow,

    Currently, within PowerApps, the Azure Data Warehouse is not a Delegable data source.

    More details about Delegable data sources supported within PowerApps, please check the following article:

    https://docs.microsoft.com/en-us/powerapps/maker/canvas-apps/delegation-list

    In default, if the data source is not a Delegable data source, you need to move your data into your app for processing locally, and you could only process 500 records at most locally. You could also consider change the "Data row limit for non-delegable queries" limit to 2000 (maximum value) within Advanced settings of App settings, then you could process 2000 records locally.

    In order to get rid of 500 records Delegation limit, as an alternative solution, please check and see if the following blog would help in your scenario:

    Best regards,

    Kris

    Hi. Nowadays, does an Azure hosted SQL database works as an on-premises SQLserver connector in terms of delegation? Because I am having delegation warnings with simple filter or sum functions.

    Thanks a lot!

    Andrés.
