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

Computer enthusiasts friends in the process of using the computer, will inevitably encounter a lot of sudden failure, the cause of these failures may be the cause of the software, may also be caused by hardware failure, or other factors ...

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

cloud computing can also be used to provide overloaded capacity. • Prepare the business unit to adopt cloud computing. Even if the IT department cannot justify the use of cloud computing, your business unit will be able to prove it. Cloud computing is a tempting business. The infrastructure of cloud computing can be configured with a credit card, and the entry and exit thresholds are low. Don't stop these efforts, learn from them. • Let cloud computing vendors know what you want. These compan

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
