If you want to return a streaming, synchronous response by writing to an OutputStream, you can make a web handler state the :body of the response as a fn, which will be called back with an OutputStream. This is described at http://pedestal.io/reference/streaming.
That page goes on to say, "The function may run as long as it needs. This will occupy a thread, so consider using a go block."
The first sentence reassuringly emphasizes that the "fn" body option is for streaming a response. But the implicit invitation to write to an OutputStream from a "go" construct seems strange. Mightn't the writes block?
