Abstract

The invention discloses a data processing method and device, a distributed network system and computer equipment. The method comprises the steps that a specified node in a distributed network receivesan access request of a page; the designated node determines a sender of the access request; and when the node corresponding to the sender is consistent with the specified node, the specified node forwards the access request to other nodes in the distributed network. According to the method and the device, the technical problems that the system cannot immediately open the data managed by the downtime node for a user to access and the availability of the system is reduced due to downtime of a part of nodes in the distributed system in related technologies are solved.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a data processing method and device, a distributed network system, and computer equipment. Background technique [0002] In a distributed storage database system, multiple distributed nodes are involved, and the cache is shared between nodes. At the same time, each node saves the status information of the pages it manages. In this case, when a node goes down, The page information managed by the down node will be restored, and most of the page status information can be obtained and restored from other nodes. However, there are currently some nodes that are down when sending page access requests, and the data cannot be recovered immediately, resulting in the loss of page information after the downtime. For example, some pages are modified by the downtime node and managed by the downtime node. The information of these pages will be lost after the downtime. At this t...
