Slowness of Look up function

Hi all, I have a problem with a duration of LookUp function and hope someone can help.
There's a requirement to get users' name in local language
1. I use Office365 Users connection to get current users' Mail
2. I have a table with two columns - Email and User Full Name (in Russian)
3. I need to find related Full Name in this table by users' email
I've tried both Excel file and SharePoint list connections, but both proceed too slowly - more than 5 minutes till the result is calculated.
There are 2500 rows in a datasource. This is pretty big but I used to proceed larger datasets much faster in other Apps.
Could anyone share any advice on how to workaround such a requirement?
Thanks in advance for your help!

Ok,

 

So first thing - on your App OnStart, have it write the russian email address to a global variable so that it's not looking that up every time the LookUp is performed:

 

App.OnStart = Set(EmailRus, ПользователиOffice365.MyProfile().Mail)

 

Then your lookup should use that variable which is now static:

LookUp(UserNamesRu;'Employee Email' = EmailRus;'Employee Name (rus) ')

 

Let me know if this helps at all,

 

Cheers,

Hi,

 

Could you share the formula you are using to do the lookUp, as I feel like this will be dependant on many factors, including how the query was written and what speed connection you are on.

 

To get the current logged in user's email address, you don't need to use the Office365 users connector as there is already an internal PowerApps function - User() - that provides this:

User().Email

Thanks for your reply.

Queries attempted:

 

First(Filter(UserNamesRu;'Employee Email' = ПользователиOffice365.MyProfile().UserPrincipalName)).'Employee Name (rus) '

LookUp(UserNamesRu;'Employee Email' = ПользователиOffice365.MyProfile().Mail;'Employee Name (rus) '))

And several variations of those. 

 

The use-case is to fetch the russian names as User() will fetch the english names as is the default language in our active directory

Hi,

 

Thank you for your reply, I'll check internal PowerApps formula also, but guess that the problem is in the datasource for looking up into. The actual formula is - LookUp(UserNamesRu; 'Employee Email' = ПользователиOffice365.MyProfile().Mail; 'Employee Name (rus) '))

UserNamesRu - the SP list with 2 columns. First is checked for matching the user mail. Already tried Excel table from a local file

Another formula I've tried is - First(Filter(UserNamesRu;'Employee Email' = ПользователиOffice365.MyProfile().Mail)).'Employee Name (rus) '

 

Both cases work too long, list contains 2,5 K rows
