Since some API calls, such as shard splitting, can take a long time and result in timeouts, we have the option of running a call asynchronously by specifying the async=<request_id> parameter in the URL. <request_id> is any ID that can be used to track the status of a particular API call. The request_id class and the status of the task are stored in ZooKeeper and can be retrieved using the REQUESTSTATUS action on the collections API.
