精通NoSQL的进来看看这种情况有什么好的解决方案?
网站A的数据库里有一个非常简单的表xx,字段:
id:自增
key:值是惟一的字符
value:值是任意字符串
网站B每天需要读取这个网站A里的xx表的数据。
我现在的做法是:
每当网站A操作xx表时,会同步往远程服务器C里的mysql数据库做同样的操作。这样网站B每天就从远程服务器C读取数据,供查询显示。但是这种方法的性能仍然是个问题,查询时需要连接远程服务器C里的mysql数据库,虽然网站B在查询获取数据后在本地做了缓存,但是我感觉还是不够满意。
最近发现NoSQL应该比较适合存储我的这个xx表,所以如果用NoSQL的话应该怎么操作比较好呢?
我还想到一个方法:
当网站A操作xx表时,每插入新的记录或者修改记录,会在某个目录下面专门为每条记录生成对应的一个txt文件,文件名就是key,文件内容是value。这样网站B每次查询数据时,curl网站a目录下有没有对应的txt文件名,如果有,就显示值。这个方法的缺点是会在网站A的某个目录下面生成数量非常多的小文件。
或者,有没有什么好的方法将xx表里的数据保存到一个文件中?然后传给网站B呢?然后网站B在本地查询等操作。缺点是每次网站xx表有更新等操作,需要将这个文件同步传到网站B那边去。

一,mysql主从,这是最简单的引流数据到线下和备份的方法。
二,谈谈楼主的想法:
1,所有数据主动同步给B是要花钱买流量的,想必你没有那么多闲置资金专门买无用的流量。
2,楼主没有描述机房部署情况,同机房不需要考虑带宽问题,只需要考虑磁盘和请求量。
楼主最好描述描述机房部署和每个服务器的使用目的细节吧。

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
