In this time, I rewrote BP( <a href="https://blueprints.launchpad.net/nova/+spec/idempotentcy-client-token" target="_blank">https://blueprints.launchpad.net/nova/+spec/idempotentcy-client-token</a> ) and I implemented proto of it.</p>



<p><br>I image below use-case.<br>User can't know instance ID when the client has gone away before user get 'create server' response of request.<br>So, User need to something which User can specify token like a mark.<br>



In the service, which can also be a problem of charging.</p><p>In this case, idempotency client token is so useful.<br>To specify the token itself by User, User can know status of server.<br>How many times User put POST method, it is guaranteed the state of the POST which was same with return of User's first POST request.</p>



<p><br>Moreover, I found that this BP( <a href="https://blueprints.launchpad.net/heat/+spec/support-retry-with-idempotency" target="_blank">https://blueprints.launchpad.net/heat/+spec/support-retry-with-idempotency</a> )<br>


is based on my blueprint.</p>
<p><br>If you have any idea about or question, please feel free to discuss anything.<br>** Also, I will attend HK summit.</p></div></blockquote><div><br></div></div></div><div>I like the idea but two comments:</div><div>

* Can you fill out the questions found in <a href="http://justwriteclick.com/2013/09/17/openstack-docimpact-flag-walk-through/" target="_blank">http://justwriteclick.com/2013/09/17/openstack-docimpact-flag-walk-through/</a></div>
<div>* Can you break down the blueprint into work items, so we can see what steps are involved</div>

<div>* Since this is for OpenStack APIs only the name client-token makes me think of keystone tokens, so I think we need a better name. </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left-width:1px;border-left-color:rgb(204,204,204);border-left-style:solid;padding-left:1ex">
