METHOD AND SYSTEM FOR DATA RECOVERY IN A DATA SYSTEM

摘要

The present teaching relates to request management and data recovery in a data system. In one example, a request is received for a transaction of data by a first node in the data system. A second node in the data system is determined based on the request. The second node is to carry out the transaction. The request is stored into a first request queue at the first node. The request is sent to the second node. A notice is obtained indicating that information associated with the transaction has been persistently stored. The request is removed from the first request queue in response to the notice.
