Thank you guys for the info, I didn't know about some of the projects.
However writing my "on-house" own stuff is not what I was considering
but adding a middleware into Keystone, nothing fancy but extensible so
it covers at least most basic use cases, pretty much like nova
middleware. So , would you like to see something like that into keystone
or you don't?
I think that's what Kevin was trying to say you didn't need to do, since
Turnstile can already do that for you :) You simply insert the Turnstile
Python WSGI middleware into the Paste deploy pipeline of Keystone, and
then you get rate limiting in Keystone.
You'd just add this into the Keystone paste.ini file:
[filter:turnstile]
paste.filter_factory = turnstile.middleware:turnstile_filter
redis.host = <your Redis database host name or IP>
And then insert the turnstile middleware in the Keystone pipeline, like so:
[pipeline:public_api]
pipeline = stats_monitoring url_normalize token_auth admin_token_auth
xml_body json_body debug ec2_extension turnstile public_service
The above should be a single line of course...
And then configure Turnstile to your needs. See:
http://code.activestate.com/pypm/turnstile/
If you wanted to do some custom stuff, check out the custom Nova
Turnstile middleware for an example:

All the best,
