It would be ideal if we could use differential deployment in the semantic layer, particularly in SSAS Tabular, or at least choose which table I want to deploy, as opposed to deploying the whole model.

If I make a change to the DAX of a single measure of a 5 gb tabular model, it is less than ideal to then deploy the entire database and process full, just to see the effect of the DAX measure in a front end tool.

Developing SSAS tabular seems to be quicker and easier in VS because of this feature.
