How can we improve Microsoft Azure Data Lake?

Column Annotation Support

We would like the ability to provide hints against columns that indicate cross-dataset relationships. Building on top of this, this foreign-key style hint could allow the visual studio tools to suggest joins across multiple streams where the hints are the same value.

    Thanks for filing this request. since we currently do not want to go through the cost of enforcing PK/FK constraints (which could be very costly given tera byte sized tables) we would need to introduce some special syntax to support this. We are adding this now to our backlog.
