there are three things you can do:

  1. create an index and see if that helps
  2. bump up the performance characteristics of your Azure SQL Database
  3. explore in-memory option for your database

7M rows is not a large dataset and if your tables are not very wide, I would also explore importing the entire data set into your model, my guess you will see good compression with that and it might be below the 250mb limit

Hi,

By In-memory option for database you mean importing in pbix or SQL Azure has some setting for this?

Actiually there are 3 tables with approx 7 mil each and then there are 5 dimension tables.

 

I will try importing in pbix and see how it goes.

 

Thanks,

Dilkush

    yes, in Azure SQL you can create in memory indexes which can potentially improve performance.
