DirectQuery for Power BI datasets and Azure Analysis Services (preview)

In Nov 2018, we released composite models, which allow you to seamlessly add multiple DirectQuery sources and imported data to your models. We have heard your feedback that you would like to do this with sources you previously live connected to, like Power BI datasets and Azure Analysis Services sources. We are excited to announce that DirectQuery for Power BI datasets and Azure Analysis Services is now in preview! This long-awaited addition allows report authors to use DirectQuery to connect to Azure Analysis Services or Power BI Datasets as sources in combination with other DirectQuery and imported data
