Integration with Spark 2.x is a great feature for Carbondata as Spark 2.x is getting the momentum gradually. This is a big effort ahead and let's take into consideration of all the complexity involved due to dramatic API level change， realizing it in phases is a good idea.

In order to make CarbonData even more popular, I think now it is good time to start considering spark2.x integration with CarbonData. Moreover, we can take this as a chance to refactory CarbonData to make it both easier to use and higher performance. Usability: Instead of using CarbonContext, in spark2 integration, user should able to 1. use native SparkSession in the spark application to create and query table backed by CarbonData files with full feature support, including index and late decode optimization. 2. use CarbonData's API and tool to acomplish carbon specific tasks, like compaction, delete segment, etc. Perforamnce: 1. deep integration with Datasource API and leveraging spark2's whole stage codegen feature. 2. provide implementation of vectorized record reader, to improve scanning performance. Since spark2 changes a lot comparing to spark 1.6, it may take some time to complete all these features. With the help of contributors and committers, I hope we can have basic features working in next CarbonData release. What do you think about this idea? All kinds of contribution and suggestions are welcomed.
