Very slow WABI-west-EUROPE-d-primairy-redirect.analysis.windows.net

[louisvp]

Dear Community,

I have created serveral Dataflows.

In Power BI Desktop I merged serveral tables.

But when I want to refresh my data I takes very before my data is refreshed.

Power BI Desktop is connecting to the source WABI-west-EUROPE-d-primairy-redirect.analysis.windows.net.

Could somesone please advise me what to do, so the refreshing of my data becomes faster?

Thanks

Hi @louisvp ,

I have a little confused about your scenario.

Please let me know the details below so that we could help further on it.

Did the data source refresh slowly in power bi desktop or power bi service?

What does this mean? What is your data source in power bi desktop? Which connector do you use in power bi desktop?

Do you have the refresh problem when you merge queries?

Best  Regards,

Hi Cherry Gao ,

Thank you for your response.

I will explain the situation.

I created serveral dataflows in Power BI Service. With fact tables and transaction tables.

In Power BI Desktop I connect to these Dataflows. This goes very fast!

And here comes the problem: In Power BI Desktop I merge the fact tables with the transaction tables (in the Power Query part of Power BI Desktop).

When I refresh all the data it takes very long (18 minutes) before all tables are update.

Attached you see some screen shots

This morning I tried the make a reference of the facttables to try if this makes the reshing of the data makes faster. But it did not make it faster.

Could you please advise me how I can make the refreshing of the tables goes faster?

Do I need to store the data from the datalow in "Azure Data Lake Storage Gen2" and merged the tables in "Azure Data Lake Storage Gen2"?

I look forward to your advise.

Thanks

Hi @louisvp ,

If your data is large, the update will be very slow for the merged query in power bi.

Do I need to store the data from the datalow in "Azure Data Lake Storage Gen2" and merged the tables in "Azure Data Lake Storage Gen2"?

I think do some changes in the datasource such as merge query instead of in query editor in power bi should be the most efficient way for your requirement.
