title: Remote service call from webclient Java : Spring Webflux
body: <p>I have a requirement where I have a 500+ ids in a request and I have to call a remote service .
  But the problem is remote service is not performant so it gets timed out . So at max I can send only 100 ids in a request. Is there a way Spring WebFlux so that I can send 500+ requests in a batch manner and at whole I can get a response .
  TIA</p>
  <p>Sample request :</p>
  <p>{&quot;ids&quot;: &quot;1&quot;,&quot;2&quot;,&quot;3&quot;,.....,
  &quot;510&quot;,&quot;511&quot;
  }</p>
  <p>Thought of using Flux.merge() but not sure .</p>
