Description

It appears that when you have big HTTP requests then vertx-http server will read all content into memory.

At first glance it does not seems an easy API to use some kind of streaming mode via java.io.InputStream as the message body type.

The vertx based Buffer appears to be read entirely into memory.

io.vertx.ext.web.handler.BodyHandler#create()

See the following code
