To reduce load on the service, retrieve operations return a maximum limit of 100 items at a time. If a request supplies no limit or one that exceeds the configured default limit, the default limit is used instead.
This behavior is called pagination. Pagination gives you the ability to limit the size of the returned data and to retrieve a specified subset of a large data set. Pagination has two key concepts: limit and marker.
- Limit is the restriction on the maximum number of items for that type that can be returned.
- Marker is a reference to an object's ID and is in the list of paged results for a particular resource. For example, if the resource is a load balancer, the marker is the load balancer ID at which to begin the list of the paged results.
To navigate the collection, you can set the
parameters in the URI. For example,
?limit=10&marker=1234 displays a
maximum of 10 load balancers in the paginated results, beginning with the
load balancer whose ID is 1234.
You can also use the
offset parameter, which is a count of the number
of objects from where the paginated list is started.
If a marker beyond the end of a list is given, an empty list is returned.
