Abstract

The present invention provides a redistribution method and system for distributed memory data, and a master control server. The method comprises: receiving memory usage data of each memory data storage server sent by a memory data storage server cluster; if the memory usage data of at least one memory data storage server is greater than a preset memory usage threshold, triggering a data redistribution process; determining data migration information, the data migration information including an IP address of a server of which data needs to be migrated, a HASH value to be migrated, the amount of service data to be migrated and an IP address of a target server; migrating the service data to be migrated to the target server according to the data migration information, the target server being a memory data storage server newly added in the memory data storage server cluster. The technical solution may support continuous service when the added server performs data redistribution.

Description

technical field [0001] The invention relates to the technical field of data storage and access, in particular to a distributed memory data redistribution method and system, and a master control server. Background technique [0002] At present, with the rapid expansion of business scope, banks and Internet companies are facing increasing risks of transaction fraud. In order to reduce the risk of these transactions, the enterprise advances the monitoring link to the transaction time, that is, after the background server receives the transaction request, it needs to provide historical transaction data within milliseconds to evaluate the risk level of the current transaction, and the newly added transaction The data is transmitted to the background server to become new historical evaluation data. How to provide historical transaction information for a large number of concurrent transactions in a short period of time, and process real-time transaction data into real-time evaluat...
