middleware distributed cluster

我是一个分布式数据库集群中间件的开发者,已经一年多一点的开发时间了,今天总结点我所知道的一些事情,给有新近来到这个领域的研发人员一点借鉴。

生活不易,赚钱不易,离开只是为多赚点钱。----学渣

我只是说我所开发过的系统:

后面文章会有详细的分析,这里只做简单的梳理。也就是你要研发分布式数据库集群中间件,需要向着哪些方面去思考。

首先我们从名字去分析我们正在从事的工作内容:

1. 分布式

需要考虑它的方向(后面详细说明)

a) 分布式中的概念

b) 分布式的模型

c) 分布式系统特性

2. 数据库集群

我们是用MySQL来作后端存储。

a) 什么是MySQL

b) 数据库集群有什么用 (分库分表是什么,横向切分纵向切分是什么)

c) MySQL在系统中的角色是怎样的

3. 中间件

中间件是什么?

上述是通过名字来判断我们需要了解哪些事情。

我们通过什么技术来实现我们的分布式数据库集群中间件?

1. 需要有网络编程(socket,多路复用,libevent,ACE)

2. 需要有多线程编程(为什么不是多进程,为什么不是单线程)

3. 内存管理(针对操作系统内存的申请与释放,怎么能够更好的管理内存)

4. 日志管理 (系统的日志怎么存放,存放在哪)

5. 元数据信息管理(重启系统,能够恢复到关机状态么?)

许许多多的问题等待我们的研究。暂时说这么多,待更新对上述问题的浅见。

What is the principle of tomcat middleware What is the principle of tomcat middleware Dec 27, 2023 pm 04:40 PM

The principle of tomcat middleware is implemented based on Java Servlet and Java EE specifications. As a Servlet container, Tomcat is responsible for processing HTTP requests and responses and providing the running environment for Web applications. The principles of Tomcat middleware mainly involve: 1. Container model; 2. Component architecture; 3. Servlet processing mechanism; 4. Event listening and filters; 5. Configuration management; 6. Security; 7. Clustering and load balancing; 8. Connector technology; 9. Embedded mode, etc.

How to handle form validation using middleware in Laravel How to handle form validation using middleware in Laravel Nov 02, 2023 pm 03:57 PM

How to use middleware to handle form validation in Laravel, specific code examples are required Introduction: Form validation is a very common task in Laravel. In order to ensure the validity and security of the data entered by users, we usually verify the data submitted in the form. Laravel provides a convenient form validation function and also supports the use of middleware to handle form validation. This article will introduce in detail how to use middleware to handle form validation in Laravel and provide specific code examples.

Node completely evacuates from Proxmox VE and rejoins the cluster Node completely evacuates from Proxmox VE and rejoins the cluster Feb 21, 2024 pm 12:40 PM

Scenario description for nodes to completely evacuate from ProxmoxVE and rejoin the cluster. When a node in the ProxmoxVE cluster is damaged and cannot be repaired quickly, the faulty node needs to be kicked out of the cluster cleanly and the residual information must be cleaned up. Otherwise, new nodes using the IP address used by the faulty node will not be able to join the cluster normally; similarly, after the faulty node that has separated from the cluster is repaired, although it has nothing to do with the cluster, it will not be able to access the web management of this single node. In the background, information about other nodes in the original ProxmoxVE cluster will appear, which is very annoying. Evict nodes from the cluster. If ProxmoxVE is a Ceph hyper-converged cluster, you need to log in to any node in the cluster (except the node you want to delete) on the host system Debian, and run the command

How to use middleware for response transformation in Laravel How to use middleware for response transformation in Laravel Nov 03, 2023 am 09:57 AM

How to use middleware for response conversion in Laravel Middleware is one of the very powerful and practical features in the Laravel framework. It allows us to process requests and responses before the request enters the controller or before the response is sent to the client. In this article, I will demonstrate how to use middleware for response transformation in Laravel. Before starting, make sure you have Laravel installed and a new project created. Now we will follow these steps: Create a new middleware Open

How to use Redis to achieve distributed data synchronization How to use Redis to achieve distributed data synchronization Nov 07, 2023 pm 03:55 PM

How to use Redis to achieve distributed data synchronization With the development of Internet technology and the increasingly complex application scenarios, the concept of distributed systems is increasingly widely adopted. In distributed systems, data synchronization is an important issue. As a high-performance in-memory database, Redis can not only be used to store data, but can also be used to achieve distributed data synchronization. For distributed data synchronization, there are generally two common modes: publish/subscribe (Publish/Subscribe) mode and master-slave replication (Master-slave).

How to use middleware for scheduled task scheduling in Laravel How to use middleware for scheduled task scheduling in Laravel Nov 02, 2023 pm 02:26 PM

How to use middleware for scheduled task scheduling in Laravel Introduction: Laravel is a popular PHP open source framework that provides convenient and powerful tools to develop web applications. One of the important features is scheduled tasks, which allows developers to run specific tasks at specified intervals. In this article, we will introduce how to use middleware to implement Laravel's scheduled task scheduling, and provide specific code examples. Environment Preparation Before starting, we need to make sure

How to use middleware for data recovery in Laravel How to use middleware for data recovery in Laravel Nov 02, 2023 pm 02:12 PM

Laravel is a popular PHP web application framework that provides many fast and easy ways to build efficient, secure and scalable web applications. When developing Laravel applications, we often need to consider the issue of data recovery, that is, how to recover data and ensure the normal operation of the application in the event of data loss or damage. In this article, we will introduce how to use Laravel middleware to implement data recovery functions and provide specific code examples. 1. What is Lara?

How Redis implements distributed session management How Redis implements distributed session management Nov 07, 2023 am 11:10 AM

How Redis implements distributed session management requires specific code examples. Distributed session management is one of the hot topics on the Internet today. In the face of high concurrency and large data volumes, traditional session management methods are gradually becoming inadequate. As a high-performance key-value database, Redis provides a distributed session management solution. This article will introduce how to use Redis to implement distributed session management and give specific code examples. 1. Introduction to Redis as a distributed session storage. The traditional session management method is to store session information.
