Hi Madhan
It is exciting news that you have just made available this work under the APL2.0 license!!! Standard RDBMS, though not as scalable as the NoSQL storage backends, might provide an easy start for many future JanusGraph projects because any devops team can have one available in the blink of an eye. Of course, this announcement deserves a more prominent spot than just this outpost of the JanusGraph community. Do you have any plans to announce this in more detail in a future blog post or conference contribution? In particular, it would be interesting to hear about the tuning of postgresql for the JanusGraph workloads (many small requests with a need for small round trip delays).
Best wishes, Marc
