-- Returns an array of @JobListEntry@ objects of the specified length. Each
-- @JobListEntry@ object contains a job\'s state, a job\'s ID, and a value
-- that indicates whether the job is a job part, in the case of export
-- jobs. Calling this API action in one of the US regions will return jobs
-- from the list of all jobs associated with this account in all US
-- regions.
--
-- This operation returns paginated results.
