Andrew Phillips commented on JCLOUDS-687:
-----------------------------------------
> Why are we duplicating service side logic (that will vary from service to
> service and deployment to > deployment) in the clients?
Agree very much with this sentiment. If we are already providing client-side
defaults and are doing this inconsistently, I definitely see the possibility
for improving that.
If, on the other hand, we're here looking to expose functionality (i.e. the
ability to set a default page size) that is only supported by some APIs, I
would rather we handle this as we do most other API-specific options and make
this one of the parameters you can pass to an {{*Options}} class.
If we need default for the overloaded versions of those calls that *don't* take
an {{*Options}} parameter, I'm open for any of the suggested solutions,
assuming we feel we indeed have a problem and a need here.
I'd agree with [~everett-toews] that trying to choose a *global* default that
works across API calls that may have completely different cost profiles sounds
tricky, so would probably lean towards a configurable per-API or even per-call
default here.
Any data we have indicating that the current situation is actually a problem
would be very useful, though.

> Project: jclouds
> Issue Type: Improvement
> Components: jclouds-core
> Affects Versions: 1.6.0, 1.7.0, 1.8.0
> Reporter: Jeremy Daggett
> Assignee: Jeremy Daggett
> Priority: Minor
> Labels: jclouds, openstack
> Fix For: 2.0.0
>
>
> Each OpenStack API has a default page size that can be returned by the
> service. The page sizes differ between APIs and there should be a way to
> reflect this in API/provider configuration. The page size is typically used
> in the list/get related operations.
> The opportunity arises to expand this to all APIs that have a default page
> size by introducing a new constant "PROPERTY_PAGE_SIZE" or
> "PROPERTY_DEFAULT_PAGE_SIZE" to the {{org.jclouds.Constants}} class.
