Thanks Piyush. You are right. Flipkart heavily uses DropWizard. In my last firm, we were using Vert-x for creating a reactive backend for web-socket requests. I wonder how DropWizard achieves this out of the box.

I’ll post the link to a repository I’d created for demoing a simple web socket request / response cycle for the benefit of others. https://github.com/isopropylcyanide/Websockets-Vertx-Flink-Kafka
