Let me tell you, Big Data engineers have an annual salary of more than 0.5 million and a technical staff gap of 1.5 million. In the future, high-end technical talents will be snapped up by enterprises. Big Data is aimed at higher talent scarcity, higher salaries, and higher salaries. Next, we will analyze the Big Data talent shortage and the employment of
