Limiting list return size

Keystone provides a method of setting a limit to the number of entities returned in a collection, which is useful to prevent overly long response times for list queries that have not specified a sufficiently narrow filter. This limit can be set globally by setting list_limit in the default section of keystone.conf, with no limit set by default. Individual driver sections may override this global value with a specific limit, for example:

To ensure API is not overloadd

[projects]
list_limit = 100

(users, roles, groups are covered by SCIM pagination)
