Client Heartbeat Renewal and Expiration Detection Method, Device, and Computer-Readable Medium

Abstract

The invention discloses a client heartbeat renewal and expiration detection method, device and computer-readable medium, wherein the method comprises: setting a time slot width and a task scheduling period of a time wheel, and dividing a preset number of time slots; Update the heartbeat records generated by each client's renewal and store them in the storage node corresponding to the time slot to keep the client alive; calculate the time slot corresponding to the current heartbeat detection time, and perform an update of Expired heartbeats are detected in the heartbeat record, and expired heartbeats are read; the client corresponding to the read expired heartbeats is offline and the expired heartbeats are cleared. The invention performs heartbeat keep-alive and expired detection on the client through the time round algorithm. When the number of clients increases greatly, the load balance of read and write pressure can be ensured, and at the same time, the conventional heartbeat scheme can avoid batch deletion of long transactions with expired heartbeats. Issues affecting other services on the server side.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a client heartbeat renewal and expiration detection method, device and computer-readable medium. Background technique [0002] When the client is online, the server needs to reserve certain resources for the client and record some status, such as session (session control), websocket connection, client login status, etc. When the client is no longer active due to inactive logout due to network reasons or other reasons, it is necessary to detect the status expiration of the client and log off the client with the expired status in time to release the pre-allocated resources. [0003] At present, the heartbeat solution is often used to detect the client's keep-alive and expiration. The conventional heartbeat solution includes heartbeat renewal and expiration detection. Heartbeat renewal means that the client sends out heartbeats at intervals to indicate that it is still a...

AI Technical Summary

Problems solved by technology

[0006] One is that distributed application scenarios are not considered. When the number of clients increases significantly, the load balancing of read and write pressure cannot be well achieved, resulting in the inability to well expand the number of clients;

[0007] Second, the server regularly deletes the expired heartbeat operation is a batch of long transactions, which can easily lead to synchronous blocking and affect other services on the server
