There are many more data stores available now.

Spark clusters are now available in V2. Since Spark is very performant and now integrates more functionalities, it has become an almost essential player in the big data world. In the previous version of ADF, Spark clusters were available via MapReduce custom activities. In this version, Spark is now a first-class citizen, so there will be no more headaches when it comes to integrating it in our data flow.
