(This course is a series of practical courses in big data projects. Based on a certain billion-level traffic background, the project realizes one-stop data collection and monitoring. Including the efficient collection of behavioral data, product data, and business data, and defining and monitoring various indicators in the data collection process. When the data acquisition link fails, the alarm can be received in time. At the same time, when encountering performance problems, we can optimize the collection process in a more targeted manner through the monitoring system. The project design is based on scenarios rather than industries, and the choice is technology-driven, focusing on the combination of various technical components to solve problems in specific scenarios. The course starts from the basics of the zero environment and proceeds step by step to help you quickly build a data collection platform for billion-level traffic scenarios.)
