有没有人知道mysql这数据库最大可以建多少张表格?
我公司现在要建支持二级域名日语的博客
我上网查了一下,只找到wordpress mu这套系统能符合要求,而且我还是用wordpress中的日语语言包,勉强可以用
但是,现在有个问题就是公司要建几十万的博客,而这套系统的数据库设计是每创建一个博客就会新创建8张表
也就是说,我想建几十万博客的话,那就要创建出几百万张表,
我觉得这个实在有点行不通,所以想问一下这里的牛人,mysql这样的数据库有没有最大上限的表格数啊?
大概是多少?
------解决方案--------------------
那么大肯定不行
你可以建立多个数据库吗
------解决方案--------------------
我想这应该受到文件系统最大文件数限制。一个MyISAM表是3个文件,所以你这个"几百万"还得乘个3。
------解决方案--------------------
数据库应该不会坏掉,应该是创建失败。以前我google过linux下可以创建的最大文件数,根目录下可创建的有限(人云亦云的说),子目录下是受到inode的数量限制(这点应该是确定的,但我也没进一步查),现在我一个目录下的文件数到10万了,网站速度没看出影响,但ll一下目录的时间可以喝点茶了。其实想像一下,目录本身也是一个数据库。
------解决方案--------------------
搞这么大的项目,用别人的服务器,总归不太好。
------解决方案--------------------
用空间商的空间?然后建一个如此庞大的项目。这个有点。。。。你们老板是不是也忒欠考虑了?带宽问题呢?数据备份呢?这些都不考虑了?
------解决方案--------------------
没有限制,主要由你的操作系统和硬件来限制。

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.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

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.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
