Processing transactions in a distributed computing system (102) that includes multiple processing modules (110) includes: storing data items in a data storage system (112) accessible to multiple processes running in the distributed computing system, where the data items are totally ordered according to an ordering rule, and at least some of the processes are running on different processing modules; and processing transactions using a plurality of the multiple processes. Processing a transaction using one of the plurality of the multiple processes includes: receiving a set of requests for accessing data items stored in the data storage system (where the requests are in a first order), obtaining locks on the data items sequentially in the first order if each of the locks is obtained within a first time interval, and, if any of the locks is not obtained within the first time interval, restarting the transaction being processed. |
