PHP页面有一个浏览量统计每秒有200并发,造成insert给mysql造成很大压力
lnmp环境,其他页面内容都做了缓存了,没有多大的负载,就是这个浏览量统计功能,给mysql带来不小的压力,请问诸位有什么解决办法吗?
怎么都说不要用MySQL来做,每秒200并发对MySQL来说不算啥难事啊。而且换成Redis、Memcached,持久化姑且不说,业务代码和运维部署量都不小。
我给你几个建议,尽量让你的运维部署和业务代码改动小一些。
你可以做主从分离,不要在一个库上高并发插入同时还做大量统计运算。分离之后,查询在从库是做(甚至是导入Hive之类专门的分布式系统来做),主库上可以去掉索引,提升插入的性能。这个方法,业务代码几乎不用任何改动(改个数据库配置文件就好了)。MySQL运维部署也可以选个业务低谷在线做。
如果你可以接受少量业务代码(PHP)改动,还有两个建议:
1. 分库,分表,每个表的数据总量小了,操作起来性能会好一些,特别是对从库的MyISAM表。你插入之前可能会有一些查询,例如查询这个IP在不在库里,以前统计过没。
2. 使用HandlerSocket插件,绕过SQL Parser,直接操作存储文件。如果业务上有可能,还可以使用bulk insert(批量插入)。MySQL InnoDB还推出了类似HandlerSocket的InnoDB NoSQL Plugin,用的memcached协议,共享InnoDB Buffer,再也不用操心MySQL和Memcached之前怎么维护数据一致性了。

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.
