[0070] 1 Overview

[0071] figure 1 An example of a data processing system 100 is shown in which deadlock avoidance techniques may be used. System 100 includes a distributed database system 102 in communication with M database clients 104 over a communication network 106 (eg, a WAN, LAN, or multi-processor system network or network-on-chip, etc.).

[0072] Distributed database system 102 includes segment D to which database D is allocated n of N nodes 108. Each node 108 includes a data store 112 that stores a segment of database D, and a data store 112 that serves as a processing module (eg, controlled by a server computer, processor, or processor core) for managing the segment of the database on data store 112. Database manager 110. The database manager 110 for a given node 108 also serves as an interface between fragments of the database on the data store 112 and entities external to that node 108, such as clients 104 and other nodes 108. although figure 1 Not expres...

Abstract

Processing a transaction in a distributed computing system (102) including a plurality of processing modules (110) includes storing data items in a data storage system (112) accessible to multiple processes running in the distributed computing system, wherein The data items are fully ordered according to an ordering rule, and at least some of the processes run on different processing modules; and a plurality of multi-processes are used to process the transaction. Using a plurality of multi-processes to process transactions includes: receiving a set of requests for accessing data items stored in the data storage system (wherein the requests are arranged in a first order); each of the locks on the data item, acquiring the locks sequentially in the first order; and if any of the locks are not acquired within the first time interval, restarting the ongoing process affairs.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims priority to US Application Serial 62 / 141,388, filed April 1, 2015. technical field [0003] The present application relates to processing transactions in distributed computing systems. In particular, the present application also relates to a distributed computing system, a computer-implemented method, and a computer-readable storage medium particularly configured to process database transactions in a distributed network of multiple data processing modules and databases, wherein the databases, for example, may be distributed in multiple database nodes. Background technique [0004] A database is a structured, persistent set of data that can be managed and queried using software programs. Transactional database management systems may include relational database systems that use database "transactions" to operate on (eg, store and manipulate) data in the database. Generally speaking, a database t...
