PHP写代码直接处理MySQL中的大量数据，卡死
有时候需要独立处理数据库中的大量数据，这个时候就自己写代码去处理，但是执行的时候，很耗资源，这个一执行，基本上网站的其它功能就全都卡在那里，动不了了，大家有什么好的解决方案吗？
实际情况是这样的，公司A系统中，有电话录音文件，这些录音文件，需要和B系统中的用户关联起来，所以，录音文件的文件名中包含了用户的电话号码，通过电话号码，在B系统中的数据库查找顾客ID，然后关联，大概有十几万条通话记录吧。PHP写了一段代码来处理，但是一执行，就系统的其它功能就卡住了，动不了

这种情况，大部分应该是SQL语句性能问题造成的，你可以尝试优化一下你的sql,附上一篇文章：MySQL性能优化的最佳20+条经验
不知道你这个是属于自动任务还是?如果是自动任务建议放在大半夜用户访问量比较少的情况下执行.不是的话不知道是读的多还是写的多呢?写的多那你估计把表给锁死了
优化一下你的sql吧，先确定瓶颈在哪？一般不在PHP哦。
跟朋友讨论的时候，然后突然想到，录音文件中是包含了录音时间的，同时每条录音，都有相应的服务信息提交到系统中，那么就可以先收集这些录音文件的时间，然后排序，取出时间段，再根据这个时间段，去读这段时间内相应的服务记录的user_id，关联读取电话号码，然后再进行文件操作，这样就可以大大降低访问数据库的频率
这样或许才是正确的思路吧

The relationship between mysql user and database
Apr 08, 2025 pm 07:15 PM
In MySQL database, the relationship between the user and the database is defined by permissions and tables. The user has a username and password to access the database.

RDS MySQL integration with Redshift zero ETL
Apr 08, 2025 pm 07:06 PM
Data Integration Simplification: AmazonRDSMySQL and Redshift's zero ETL integration Efficient data integration is at the heart of a data-driven organization. Traditional ETL (extract, convert, load) processes are complex and time-consuming, especially when integrating databases (such as AmazonRDSMySQL) with data warehouses (such as Redshift). However, AWS provides zero ETL integration solutions that have completely changed this situation, providing a simplified, near-real-time solution for data migration from RDSMySQL to Redshift. This article will dive into RDSMySQL zero ETL integration with Redshift, explaining how it works and the advantages it brings to data engineers and developers.

1. Use the correct index to speed up data retrieval by reducing the amount of data scanned select*frommployeeswherelast_name='smith'; if you look up a column of a table multiple times, create an index for that column. If you or your app needs data from multiple columns according to the criteria, create a composite index 2. Avoid select * only those required columns, if you select all unwanted columns, this will only consume more server memory and cause the server to slow down at high load or frequency times For example, your table contains columns such as created_at and updated_at and timestamps, and then avoid selecting * because they do not require inefficient query se
