Node switching method, electronic equipment and computer readable storage medium

Abstract

The embodiment of the invention relates to the technical field of Internet, in particular to a node switching method, electronic equipment and a computer readable storage medium. The node switching method comprises the following steps: if a main management node of the distributed database is abnormal, judging whether a plurality of standby management nodes of the distributed database have consistent copies or not; wherein the distributed database comprises management nodes and non-management nodes corresponding to the management nodes, and the management nodes comprise a main management node and a plurality of standby management nodes; if at least one standby management node has the consistent replica, determining a new main management node in the standby management nodes with the consistent replica; and switching the non-management node according to the new main management node. The node switching method provided by the embodiment of the invention aims to improve the logic leakproofness of the node switching process, so that the switching mode is more reasonable and simpler, and the distributed database is ensured not to lose data, thereby ensuring that each service can run normally.

Description

technical field [0001] The embodiments of the present application relate to the field of Internet technologies, and in particular, to a node switching method, an electronic device, and a computer-readable storage medium. Background technique [0002] With the rapid development of Internet technology, the scale of industrial application systems has expanded rapidly, and the amount of data generated by industrial applications has exploded. Especially in industries that value data security such as the financial industry and technology industry, centralized databases can no longer meet the needs of Taizi Section level (Terabyte, referred to as: TB level) or even petabyte level (Petabytes, referred to as: PB level) data. Industries increasingly need a method that can process data quickly and respond to user access in a timely manner, as well as centrally analyze, manage, and maintain data. [0003] Therefore, a distributed database with the characteristics of transparency, data ...
