This podcast provides a beginner-friendly guide to reading the TiDB source code, focusing on practical methods rather than theoretical overviews. It details setting up the necessary development environment (including using Golang and an IDE like IntelliJ IDEA). The author suggests starting with the main function or the dispatchfunction as entry points for understanding the code's structure and functionality. The post emphasizes understanding the code's lifecycle and how user requests are processed, using the dispatch function as a key example. Finally, it outlines future topics the series will cover, promising further insights into TiDB's inner workings.
