The "reactive" buzzword has been conspicuously absent from this l=
ist. <br>
I'll try to fill this much needed gap.<br>
<br>
I've recently watched a presentation by Jafar Husain<br>
<br>
<a href=3D"http://www.infoq.com/presentations/netflix-reactive-rest" target=
=3D"_blank">http://www.infoq.com/presentations/netflix-reactive-rest</a><br=

<br>
where he describes something he calls "Reactive REST". I agree on=
the <br>
"reactive", however I have doubts about the "REST". In =
this particular <br>
case, all communication between a client and a server is over persistent <b=
r>
connection to a single endpoint. If there's anything resembling <br>
resources, they are not identified by URIs. The persistent connection <br>
IMHO is a case of "conversational" state that REST is rather oppo=
sed to. <br>
No HATEOAS in sight.<br>
<br>
What I'm pondering is whether an API can be RESTful and reactive at the=
<br>
same time or if is impossible as a matter of principle. AFAICT, a <br>
reactive API requires some way for the server to send events to the <br>
client. I don't think polling qualifies, which leaves a persistent <br>
connection. In effect, the server has to keep some amount of state for <br>
each session.<br>
<br>
Keeping session state has traditionally been regarded as a hindrance to <br=
>
scalability. Has technology advanced so much, eg with asynchronous, <br>
event-driven ("reactive") servers, that this is no longer a probl=
em?<br>
<br>
Frankly, I'm lacking experience with systems where this kind of <br>
scalability would be required, so I'd happily use persistent <br>
connections, at least to begin with. Nonetheless, I'm interested in you=
r <br>
insights.<br>
