Abstract

The invention discloses a node determination method, device and storage medium of a distributed system. Among them, the method includes: obtaining the first session information and the first locking information of the first node in the distributed system, and the second session information and the second locking information of the second node; through the first session information and the second The session information judges whether the session created by the first node and the second node is successfully created, and judges whether the first node and the second node preempt and lock successfully through the first locking information and the second locking information, so that the first node A primary node and a secondary node are determined between the secondary node and the primary node, wherein the primary node is used to process transaction requests received by the secondary node. The invention solves the technical problem that the nodes of the distributed system have relatively low determination fault tolerance.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a method and device for determining a node of a distributed system and a storage medium. Background technique [0002] In a distributed system, in order to achieve consensus consistency, the leader election of the cluster needs to be involved. The classic consensus consensus algorithm Paxos plays an important role in cluster leader election. It and its derived algorithms occupy a large market for cluster leader election, making outstanding contributions to the field of big data distributed systems; [0003] However, the above cluster leader election method is only for multi-node cluster scenarios, and in the two-node scenario, the shortcomings of the above cluster leader election method's low fault tolerance are fully exposed. For example, when network fluctuations occur, it will This leads to an abnormal election, which in turn leads to the phenomenon of multiple masters, ...
