</div>The proof of concept patch for doing it this way is at<br>
<a href="https://review.openstack.org/#/c/20412/" target="_blank">https://review.openstack.org/#/c/20412/</a> . The queries aren't amazing,<br>
but they're not that awful either. It currently hardcodes 'instance',<br>
but that's just a lookup table to fix.<br>
<br>
This doesn't mean I disagree about the right way to do it - if you think<br>
tags will serve a purpose in glance/quantum/etc beyond EC2 API<br>
compatibility, then that's the right way to do it. I'm just saying that<br>
if it's not useful in it's own right, getting a cheap and cheerful EC2<br>
API compatibility fix a different way doesn't introduce huge amounts of<br>
awfulness.<br></blockquote><div><br></div><div>I agree with Vish about <span style="background-color:rgb(255,255,255);color:rgb(34,34,34);font-family:arial,sans-serif;font-size:13px">leaning towards 1, because I think tags will be useful for the OpenStack API as well.</span></div>
