Matt's Blog（柳年思水）is a personal technical blog powered by Hexo. Its content covers topics such as Apache Flink, Kafka, Calcite, BookKeeper, Kubernetes, and readings of distributed systems papers. It is not a commercial product or course platform, but more like a public knowledge base built up over time by a backend/big data engineer.
The site provides a homepage article feed, archives, categories, tags, subscription options, and an about page. Its core value lies in the articles themselves: for example, the conversion chain from the Flink DataStream API to StreamGraph, JobGraph, and ExecutionGraph; Flink Master/JobManager/TaskManager mechanisms; Kafka Exactly-Once transaction implementation; and an interpretation of the Chandy-Lamport distributed snapshot paper. Articles typically include background explanations, source code snippets, architectural concepts, and the author’s personal summaries, making them suitable for in-depth study.
The site’s content is free to read. The copyright notice states that original and translated articles are licensed under the Creative Commons Attribution 4.0 International License. Non-commercial reposts must credit the author and include the original link; commercial use or adaptations require separate authorization. No paid memberships, course purchases, or advertising monetization were observed.
The main advantage is its clear technical depth, especially in Flink and distributed systems. Systematic source code analysis of this kind is not very common among Chinese-language resources. The articles are also well structured and helpful for engineers who want to understand underlying principles. The downside is that the site appears to have been updated some time ago, with the latest crawled articles concentrated around 2020. Versions such as Flink 1.9/1.10 and Kafka 2.0 may differ from the current ecosystem. In addition, comments rely on Disqus, which may be unstable on mainland Chinese networks.
It is suitable for readers with a background in Java, backend development, big data, or distributed systems, especially as a supplement for source code reading, paper comprehension, and interview preparation. It is not very suitable for absolute beginners, nor should it be used as the sole reference for hands-on documentation for the latest versions.
The main site is a standard static blog, so its Chinese pages are likely to be directly accessible. However, external resources such as Disqus comments, Twitter, and LinkedIn may be restricted in mainland China. Reading the main article content is usually not significantly affected.
