Abstract

The invention discloses a node determination method and device of a distributed system and a storage medium. The method comprises the following steps: acquiring first session information and first locking information of a first node and second session information and second locking information of a second node in the distributed system; judging whether a session created by the first node and the second node is successfully created or not according to the first session information and the second session information, and judging whether the first node and the second node are successfully preempted and locked or not according to the first locking information and the second locking information, so as to determine a primary node and a secondary node between the first node and the second node, wherein the primary node is used for processing the transaction request received by the secondary node. According to the invention, the technical problem that the determination fault-tolerant capability of the nodes of the distributed system is relatively low is solved.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method and device for determining a node in a distributed system and a storage medium. Background technique [0002] In a distributed system, in order to achieve consensus consistency, it is necessary to involve the leader election of the cluster. The classic consensus consensus algorithm Paxos plays a very important role in the cluster leader election, and its derivative algorithm occupies a large market in the cluster leader election, making outstanding contributions to the field of big data distributed systems; [0003] However, the above method of cluster leader election is only for multi-node cluster scenarios, and in the case of two-node scenarios, the defects of the above method of cluster leader election are exposed. For example, when network fluctuations occur, the The election is abnormal, which in turn leads to the phenomenon of multiple masters, that is, the phenom...
