gnocchi metric list times out

[gordon chung]

gnocchi metric list does not work. it is basically guaranteed to timeout

[gordon chung (chungg)]

this happens because gnocch metric list is not configured to paginate or anything so blindly running the command will return tens of thosands of metrics. we should either paginate the results or enforce a resource_id

[Julien Danjou (jdanjou)]

Yes, completely agree. So what's the API-WG reco or what other projects do by default?

We already support pagination AFAIK (or we can do it easily with oslo.db as we do in other places) so I'd say having a default limit of N and then using paging to get the rest would be a good idea.
