To reduce load on the service, retrieve operations return a maximum limit of 1000 items at a time by default. 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 is handled by two parameters in Cloud Block Storage: limit and offset.
Limit is the restriction on the maximum number of items that are returned.
Offset is a count of the number of objects from where the paginated list is started.
To navigate the collection, you can set the
parameters in the URI. For example,
?limit=100&offset=10 displays a
maximum of 100 items from the retrieve operation in the paginated results with
an offset of 10 items.
