Guide to Alibaba Cloud Community Big Data Resources and Learning Path

Preface – The author references a previous article "I Study Big Data on Bilibili" and a prior outline "From Zero to Big Data Expert Learning Path Guide". The new version, completed by January 1 2022, reflects rapid changes in the big‑data field and updates the skill model based on personal experience.

Cloud Community – Alibaba Cloud Developer Community covers cloud computing, IoT, big data, cloud‑native, databases, AI, micro‑services, security, development, and operations. It offers a one‑stop platform for sharing, learning, certification, tools, resources, competitions, and entrepreneurship, targeting the full developer lifecycle.

The big‑data section can be accessed at https://developer.aliyun.com/community/bigdata, where sub‑directories lead to various specialized resources.

Key Usage – The community hosts a vast amount of content, including official product articles, e‑books, and Q&A. Users can find high‑quality electronic books (the "藏经阁"), such as the renowned "Java Development Manual" and big‑data titles like "Redis Best Practices" and "Apache Flink Top Ten Technical Challenges".

Within the "藏经阁" there is a "Career Development" column offering guidance for developers with less than five years of experience, outlining technology stacks and future advancement directions.

Product Discussion (Q&A) – The Q&A area serves as a robust forum for big‑data questions, often requiring deep and broad technical knowledge. Queries like "How to calculate PV/UV?" depend on context (Spark vs. Flink, real‑time vs. SQL), illustrating the complexity of big‑data problem solving.

Learning Path & Advancement – The section provides clear learning routes and a self‑assessment area to test mastery of the presented skills.

Open Courses – Industry experts, CTOs, and technical leaders share high‑definition videos on specific domains (e.g., search for e‑commerce), helping learners understand real‑world implementations beyond isolated code snippets.

Activities & Bootcamps – This area lists online bootcamps and events, including open‑source and Alibaba Cloud‑based challenges such as the Apache Flink Geek Challenge.

Popular Tech Circles – Highlights high‑traffic circles that indicate emerging trends, encouraging readers to explore beyond their current specialization.

Conclusion – The Alibaba Cloud Community’s big‑data section offers a wealth of high‑quality resources that surpass many blogs in both breadth and depth, making it a valuable hub for anyone seeking to deepen their big‑data expertise.
