The popularity of Chat GPT and GPT-4 has shown us the power of artificial intelligence. Behind artificial intelligence, in addition to algorithms, what is more, important is massive data. Around the data, we have built a large-scale complex system, the value of which mainly comes from business intelligence (Business Intelligence, BI) and artificial intelligence (Artificial Intelligence, AI). Due to the rapid growth of data volumes in the Internet age, data infrastructure work, and best practices are also evolving rapidly. In the past two years, the core system of the data infrastructure technology stack has been very stable, and the supporting tools and applications are also growing rapidly.
