Problems solved by technology

If the data is not written to the Slave node after degrading to asynchronous replication, it is easy to cause this data loss, resulting in data confusion in the system
Moreover, when the Master node fails, the corresponding Slave node needs to be upgraded to the Master node. However, due to inaccurate fault judgment or false positives by the system, after the Slave node is upgraded to a new Master node, the original Master node remains In the operation situation, writing data at this time will cause the "double writing" problem of data writing to two Master nodes, which further aggravates the data confusion in the system, resulting in low data stability

Abstract

Embodiments of the invention disclose a database management method and a database system, and relate to the technical field of databases. The stability of data reading / writing in the system can be improved. The method comprises the steps of receiving to-be-written data sent by user equipment, and writing the to-be-written data into a Master node in a cluster; transmitting the to-be-written data to at least two Slave nodes corresponding to the Master node and located in a partition where the Master node is located from the Master node, and detecting whether the Master node receives a response message sent by at least one Slave node, wherein the response message is sent by the Slave node successfully written with received data; and if the Master node receives the response message sent by the at least one Slave node, sending a notification message to the user equipment, wherein the notification message is used for representing a database successfully written with the to-be-written data. The method is suitable for data reading / writing management of a relational database.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a database management method and a database system. Background technique [0002] Relational database is a type of database widely used at present. In the construction of relational database, it usually needs to be clustered by multiple data servers. MySQL (a relational database management system) is currently a commonly used relational database management system and is used to manage clusters. [0003] In the current cluster solution based on MySQL design, it is necessary to configure the nodes to assume the role of Master and Slave respectively. The data submitted by the user device will be written to the Master node and the Slave node in the form of semi-synchronous replication, thereby improving the data writing process. security. [0004] In the actual operation of the system, many problems such as network congestion, data writing errors, and equipment failures will also...
