wtf is flink-training-course?

This repository is a curated index of Chinese-language video training sessions for Apache Flink, produced by the official Apache Flink Community China group. Apache Flink is a data processing system used by companies to analyze large streams of information in real time, for things like monitoring user activity, processing transactions, or building data warehouses. The README serves as a course catalog rather than a code project. It lists dozens of recorded sessions organized into topic areas: fundamentals, operations and deployment, real-time data warehouse use cases, ecosystem integrations with other tools, and community growth for people who want to contribute to Flink itself. Each entry names the speaker, their affiliation (many are engineers from Alibaba or other large Chinese tech companies), and links to the slide deck and a video replay on Bilibili. The course has been organized in multiple seasons, with Season 3 still listed as ongoing at the time of the last update. Topics covered across the sessions include monitoring and alerting, job tuning, resource management internals, SQL-based application development, running Flink on Kubernetes, integration with tools like HBase and Apache Pulsar, and the Python API for Flink called PyFlink. This repository does not contain runnable code. It is a learning resource and reference index for practitioners who want structured Chinese-language instruction on Flink, whether they are just getting started or looking for deeper technical sessions on specific subsystems.
