    I've solved my problem

     

    If someone encounter the same problem here what I did : 

     

    First I've created a view of my big table, with only the needed columns.

    As my datas are dated from 1994 to today, I have 2 view : one for datas before 2014 and for datas since 2014 (They don't really need very old datas in my company)

     

    Then i've tried to DirectQuery but it was still very slow.

    I've disabled the options of type detection / relations in the Loading Data part

     

    Then I've imported it and it worked perfectly fine, it's very fast (1 or 2 seconds of loading with millions of rows)
