This section explores the elasticjob failover mechanism. We know that Elasticjob is a distributed task scheduling framework based on quartz, where distributed data is distributed, and the core design concept of elasticjob is that a task executes on multiple nodes, and each node processes part of the data (task pending data shards). If a task node is down, and a task is scheduled, a portion of the data will not be processed, in order to solve the task node downtime caused by the task of a schedul

0. Overview:In general, in order to improve the game speed, the online player's data will be cached in memory. If there are data updates, only the cached data in memory is updated, rather than updating the database directly. The cached data is periodically written back to the database (for example, 5-minute writes). When the server goes down, all the data from the last database update to the outage will be lost, the so-called back file. This part of t

algorithm is that fault tolerance and extensibility are not good. Fault tolerance refers to whether the whole system can run correctly and efficiently when one or several servers in the system become unavailable, and extensibility refers to whether the whole system can run correctly and efficiently when a new server is added.Now assume that a server is down, in order to fill the vacancy, to remove the outage server from the numbered list, the followi

At this time because the outside VIP has been transferred to the Server2,web request will be sent to Server2 Nginx. Nginx detects a server1 outage and no longer forwards the request to the Server1 php-fpm.

An RDB maximizes the performance of Redis: The only thing the parent process has to do when saving an Rdb file is to fork out a child process, and the child process will handle all subsequent save work, and the parent process does not have to perform any disk I/O operations. An RDB recovers a large data set faster than AOF. rdb persistence disadvantage If you need to avoid data loss in the event of a ser
