Just out of interest, have you tried using Skyline as a dashboard instead of the horizon?

I believe keystone should already support pagination. The better question is what horizon uses as client - openstacksdk or python-keystoneclient. As I believe a lot of issues are solved with openstacksdk as of today, and switching to it also would match community goal. So imo that might be good thing to contribute to:)

Too whom it may concern,

I am relatively new to contributing to OpenStack and therefore am not sure who to direct this question too. I have the following issue. The firm I am currently working at is running OpenStack at sale with circa 6000 different projects. Whenever we try to access a projects tab via horizon we experience a timeout (accessing through the API works fine). To that end we were hoping to implement something akin to pagination or filtering. I was hoping to work on this and contribute the outcome to OpenStack. Is this something worthwhile and which group should I talk to; keystone, horizon or both ? I apologise in advance if I have missed something.

Best Regards,
Sergey
