To whom it may concern, We were hoping to propose something akin to filtering/dynamic listing to the horizon team in order to rectify the issue. In turn, for the keystone team, we were wondering whether there is anything we can do with the API in order to simplify the aforementioned horizon proposal; we are hoping to get both teams on board. Subsequently, should we reach an agreement, we would be more than happy to create a bug report, follow that with (a) blueprint(s) and proceed immediately; unless any other terms of engagement are amicable. Please let me know how everyone would like to proceed. Best Regards, Sergey Drozdov Software Engineer The Hut Group

It was a conscious decision by the keystone team back in 2015 as far as we can tell. There was a large discussion on the mailing list regarding this that seemed to have left this issue unresolved (most specifically around user pagination, but this seems to have affected project / domain elements as well).

Ultimately what we're seeking to do is start a discussion within the keystone / horizon (and potentially skyline) community about how we can rectify the current issues we're facing around the usability of the UX portion of keystone elements. Eg, if pagination isn't the way the keystone community wants to go should we look at instead having dynamic filtering instead in the UI? Are there any other options that people can think of that might be a better way forward?

Unfortunately pagination was removed from keystone in the v3 api and as far as we're aware it was never re-added.
This is quite concerning, and a quick look at the code confirms it. Mostly. There are remnants of "hints" and SQL Query filtering, but the internal limit is just a truncation which seems bad as well.

This seems like a fundamental performance oriented feature because the overhead in data conversion can be quite a bit when you have a large number of well... any objects being returned from a database.
Does anyone know if a bug is open for this issue? Danny Webb Principal OpenStack Engineer The Hut Group <http://www.thehutgroup.com/>
