近日，全球最大的自由、免费、内容开放的网络百科全书Wikipedia正式从MySQL迁移到MariaDB数据库。
在做正式迁移前Wikipedia做了大量的准备工作，包括兼容性测试和性能测试，详情请看官方说明。此前，2012年CSDN研发频道曾报道过Wikipedia开发者Asher Feldman宣称将英文维基的一个（slave）数据库从MySQL5.1 + Facebook补丁集迁移到了MariaDB 5.5.28。
如今，时隔将近半年，Wikipedia正式完成迁移。
MariaDB是一个社区驱动的、采用XtraDb存储引擎的MySQL分支版本，由MySQL创始人Michael Widenius带领开发，遵循GPL v2.0协议开源。
与MySQL相比较，MariaDB的优势在于：
- Maria存储引擎
- PBXT存储引擎
- XtraDB 存储引擎
- FederatedX存储引擎
- 更快的复制查询处理
- 线程池
- 更少的警告和bug
- 运行速度更快
- 更多的Extensions (More index parts, new startup options etc)
- 更好的功能测试
- 数据表消除
- 慢查询日志的扩展统计
- 支持对Unicode的排序
据Solidot 的报道获悉：MySQL是世界上最流行的开源关系数据，它的名字取自于创始人Michael "Monty" Widenius的长女“My”。2008年，Sun收购MySQL；2009年，甲骨文收购了Sun，MySQL落入了与开源社区关系紧张的甲骨文手中。Widenius与他的旧团队在2009初创建了MySQL的分支MariaDB，它的名字取自于Widenius的幼女“Maria”，他希望通过保留核心开发者和日益增长的社区帮助MariaDB挑战甲骨文的MySQL。
Wikipedia宣布从MySQL迁移到MariaDB，部分原因是甲骨文的MySQL有免费版和企业版，企业版的新功能没有公开源码，而MariaDB则没有这方面的问题。

MySQL BLOB: how to optimize BLOBs requestsMay 13, 2025 am 12:03 AMOptimizing MySQLBLOB requests can be done through the following strategies: 1. Reduce the frequency of BLOB query, use independent requests or delay loading; 2. Select the appropriate BLOB type (such as TINYBLOB); 3. Separate the BLOB data into separate tables; 4. Compress the BLOB data at the application layer; 5. Index the BLOB metadata. These methods can effectively improve performance by combining monitoring, caching and data sharding in actual applications.

MySQL: String Data Types and Indexing: Best PracticesMay 12, 2025 am 12:11 AMBest practices for handling string data types and indexes in MySQL include: 1) Selecting the appropriate string type, such as CHAR for fixed length, VARCHAR for variable length, and TEXT for large text; 2) Be cautious in indexing, avoid over-indexing, and create indexes for common queries; 3) Use prefix indexes and full-text indexes to optimize long string searches; 4) Regularly monitor and optimize indexes to keep indexes small and efficient. Through these methods, we can balance read and write performance and improve database efficiency.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
