Abstract:
Data storage system and method for managing transaction requests in the data storage system utilizes prepare requests for a transaction request for multiple data storage operations. The prepare requests are sent to selected destination storage nodes of the data storage system to handle the multiple data storage operations. Each prepare request includes at least one of the multiple data storage operations to be handled by a particular destination data store node and a list of the destination storage nodes involved in the transaction request.

Claim (Index 7):
The method of  claim 6 , wherein executing the recovery operation comprises:\n searching for a target transaction in a write ahead log of a particular data store node, wherein the target transaction includes a prepare request and a corresponding commit request in the write ahead log of the particular data store node; using a list of the data store nodes involved in the target transaction in one of the prepare and commit requests of the target transaction, searching the write ahead logs of the other data store nodes in the list for corresponding prepare requests for the target transaction, corresponding commit entries for the target transaction or appropriate maximum transaction identifications that indicate transactions with transaction identifications equal to or less than the maximum transaction identifications have been handled; and writing either a commit record or an abort record for the transaction request depending on results of the searching of the write ahead logs of the data store nodes in the list.
