Are there Application Variables in Vertx?

I am looking to set custom objects in Application scope variables so that vertx has access to it across all micro-service requests. I couldn't find anything in Vertx documentation. In Java EE Servlet the code for similar feature is 

getServletContext().getAttribute("application_data")
getServletContext().setAttribute("application_data", data);

For global data, you should simply use shared data. This has the additional benefit of being accessible across the cluster.

The following code uses a local map:

SharedData sd = vertx.sharedData();
LocalMap<String, String> map1 = sd.getLocalMap("mymap1");
map1.put("foo", "bar");

Reading is similarly easy:

String val = map1.get("foo");

The documentation is on this page
