游戏合服 有一些表的主键是自增id,这部分表的合并有什么好的方案?
打算用一个php脚本完成合服功能,目前数据的备份、过滤以及玩家id的更新已经都完成,就是数据导入时,一些表的主键是自增id,目前没有想到特别好的方案。请各位高手给我一些建议,如何能兼容性很好的解决这个问题?

既然会合一次,就会合第二次,建议直接一次到位改成UUID,方便以后再合服
先写一个[表,id,服务器]=>[UUID]的转换,然后先把原来的表全都按照UUID重新写一遍,然后让生产环境原来写一份的改成写两份(旧表和UUID新表),然后慢慢把读切换到新表上,最后旧表上只有写没有读了就可以丢掉了。这时候就无论怎么合服都丝般顺滑毫无风险了
曾经帮助运帷大哥合服,遇到同样的问题。我们的解决方案是写了一个小程序 先SELECT出来,再INSERT进去。
A服的最大自增ID是100的话,就把B服的所有自增ID增加100。
没实践过,以前在哪看到过这种方案,目测是可行的,实际上的情况不太清楚。
仅供参考。。
最简单的方案是以大区id作为前缀。
或者是以物理服务器的id作为前缀,每个数据库的id肯定是不同的。
还有一种方案,是根据服务器建表,把不同服务器的玩家数据打散到不同的表中(虽然是在一个数据库里),虽然管理上比较麻烦,但是数据不会冲突
不使用自增型数字id作为主键了,直接使用uuid作为主键。不管你是合服还是做分布式,都是最简单的方式。

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

I encountered a tricky problem when developing a small application: the need to quickly integrate a lightweight database operation library. After trying multiple libraries, I found that they either have too much functionality or are not very compatible. Eventually, I found minii/db, a simplified version based on Yii2 that solved my problem perfectly.

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

Article summary: This article provides detailed step-by-step instructions to guide readers on how to easily install the Laravel framework. Laravel is a powerful PHP framework that speeds up the development process of web applications. This tutorial covers the installation process from system requirements to configuring databases and setting up routing. By following these steps, readers can quickly and efficiently lay a solid foundation for their Laravel project.

MySQL and phpMyAdmin are powerful database management tools. 1) MySQL is used to create databases and tables, and to execute DML and SQL queries. 2) phpMyAdmin provides an intuitive interface for database management, table structure management, data operations and user permission management.

Compared with other programming languages, MySQL is mainly used to store and manage data, while other languages such as Python, Java, and C are used for logical processing and application development. MySQL is known for its high performance, scalability and cross-platform support, suitable for data management needs, while other languages have advantages in their respective fields such as data analytics, enterprise applications, and system programming.
