@apoorv-kumar agree about enterprise users; we’ll need to eventually build tools to support them and their needs wrt legacy solutions. Making it easy to port their data over from tables to Dgraph would be a step in the right direction.

We definitely want to make it really easy for developers, students, sys admins, and other enthusiasts to get started with Dgraph and play around with it. You have some great suggestions that we should take a look at.
