Abstract

The invention is applicable to the field of communication technology, and provides a method and a system for maintaining the consistency of distributed data. The method comprises the following steps: when receiving a reloading request sent by a user, a monitoring management node sends a reloading instruction to a main transaction node; the main transaction node sends the reloading instruction to a first spare transaction node and a second spare transaction node; the first spare transaction node and the second spare transaction node cache a transaction instruction of the main transaction node according to the reloading instruction; the first spare transaction node creates a recovery data set according to transaction data, and sends creation completion information to the monitoring management node and the second spare transaction node after creating the recovery data set; and the second spare transaction node recovers the transaction data according to the recovery data set, and replays the transaction data according to the cached transaction instruction of the main transaction node after recovering the transaction data. The method and system provided by the invention maintain the consistency of the distributed data.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method and a system for maintaining the consistency of distributed data. Background technique [0002] With the gradual expansion of the scale of securities transactions, the construction of programmatic and quantitative trading platforms has also received increasing attention. The existing securities trading system adopts a distributed system. In the distributed trading system, it is necessary to ensure the data consistency of the trading nodes in the same group. [0003] In the prior art, after a certain transaction node fails, it is difficult to restore the data of the normal operation transaction node to the repaired node without interrupting or affecting the normal operation of the transaction node Therefore, even after the faulty transaction node is repaired, it is difficult to restore the data of the transaction node. Contents of the invention [00...
