public void example1(Vertx vertx) {

    SharedData sd = vertx.sharedData();

    LocalMap<String, String> map1 = sd.getLocalMap("mymap1");

    map1.put("foo", "bar"); // Strings are immutable so no need to copy

    LocalMap<String, Buffer> map2 = sd.getLocalMap("mymap2");

    map2.put("eek", Buffer.buffer().appendInt(123)); // This buffer will be copied before adding to map

    // Then... in another part of your application:

    map1 = sd.getLocalMap("mymap1");

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

    map2 = sd.getLocalMap("mymap2");

    Buffer buff = map2.get("eek");
