Horizontal Fusion
Can anyone explain what the Desktop Preview feature "Horizontal Fusion" is? I can't seem to find any documentation anywhere.
Please check this latest anouncement by Microsoft:

Horizontal fusion will decrease the number of queries send to the source system which will increase performance especially in Direct Query mode, but also in Import mode (however the gains shall be less visible).
