Hi Gilles, I hope you enjoyed your Summit!?<br><br>Did you had any interesting talk to report about our little initiative ?<br><div class="gmail_quote"><div dir="ltr">Le dim. 6 mai 2018 à 15:01, Gilles Dubreuil <<a href="mailto:gdubreui@redhat.com">gdubreui@redhat.com</a>> a écrit :<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">

<p>Akihiro, thank you for your precious help!<br>
</p>
<p>Regarding the choice of Neutron as PoC, I'm sorry for not
providing much details when I said "because of its specific data
model",<span style="color:rgb(34,34,34);font-family:sans-serif;font-size:14px;font-style:normal;font-variant-ligatures:normal;font-variant-caps:normal;font-weight:400;letter-spacing:normal;text-align:start;text-indent:0px;text-transform:none;white-space:normal;word-spacing:0px;background-color:rgb(255,255,255);text-decoration-style:initial;text-decoration-color:initial;float:none;display:inline"></span><br>
effectively the original mention was "its API exposes things at
an individual table level, requiring the client to join that
information to get the answers they need".<br>
I realize now such description probably applies to many OpenStack
APIs.<br>
So I'm not sure what was the reason for choosing Neutron. <br>
I suppose Nova is also a good candidate because API is quite
complex too, in a different way, and need to expose the data API
and the control API plane as we discussed.<br>
</p>
<p>After all Neutron is maybe not the best candidate but it seems
good enough. <br>
</p>
<p>And as Flint say the extension mechanism shouldn't be an issue.</p>
<p>So if someone believe there is a better candidate for the PoC,
please speak now.</p>
<p>Thanks,<br>
Gilles</p>
<p>PS: Flint, Thank you for offering to be the advocate for Berlin.
That's great!<br>

<div>Hi Akihiro,<br>
<br>
Thanks a lot for this insight on how neutron behave.<br>
<br>
We would love to get support and backing from the neutron team
in order to be able to get the best PoC possible.<br>

<div dir="auto">Someone suggested neutron as a good choice

<div dir="auto">@Gilles, if I goes to the berlin summitt I could
definitely do the networking and relationship work needed to get
support on our PoC from different teams members. This would help
to spread the world multiple time and don’t have a long time
before someone come to talk about this subject as what happens
with the 2015 talk of the Facebook speaker.</div>

<div>
<div>On the other hand, I am not sure this is the right
reason to choose 'neutron' only from this reason. I
would like to note "its specific data model" is not the
reason that makes the progress of API versioning slowest
in the OpenStack community. I believe it is worth
recognized as I would like not to block the effort due
to the neutron-specific reasons.</div>
<div>The most complicated point in the neutron API is that
the neutron API layer allows neutron plugins to declare
which features are supported. The neutron API is a
collection of API extensions defined in the neutron-lib
repo and each neutron plugin can declare which subset(s)
of the neutron APIs are supported. (For more detail, you
can check how the neutron API extension mechanism is
implemented). It is not defined only by the neutron API
layer. We need to communicate which API features are
supported by communicating enabled service plugins.</div>
<div><br>
</div>
<div>I am afraid that most efforts to explore a new
mechanism in neutron will be spent to address the above
points which is not directly related to GraphQL itself.<br>
</div>
<div>Of course, it would be great if you overcome
long-standing complicated topics as part of GraphQL
effort :)<br>
</div>
<div><br>
</div>
<div>I am happy to help the effort and understand how the
neutron API is defined.</div>

<br>
Few of us recently discussed [1] how GraphQL [2], the
next evolution <br>
from REST, could transform OpenStack APIs for the
better.<br>
Effectively we believe OpenStack APIs provide perfect
use cases for <br>
GraphQL DSL approach, to bring among other advantages,
better <br>
performance and stability, easier developments and
consumption, and with <br>
GraphQL Schema provide automation capabilities never
achieved before.<br>
<br>
The API SIG suggested to start an API GraphQL Proof of
Concept (PoC) to <br>
demonstrate the capabilities before eventually extend
GraphQL to other <br>
projects.<br>
Neutron has been selected for the PoC because of its
specific data model.<br>
<br>
So if you are interested, please join us.<br>
For those who can make it, we'll also discuss this
during the SIG API <br>
BoF at OpenStack Summit at Vancouver [3]<br>
