During application maintenance for the customer, I noticed some performance problems under high load conditions. Theoretically, increasing the load on the application will reduce the performance, but I think the performance drop rate is much higher than the load increase. At the same time, I also found that, performance can be improved by changing the logic of the application. To learn more about this, we need to perform some performance analysis. At this time, we naturally need to use some perf

, you want to get as much information as possible about the use case. The volume of data alone does not determine whether it helps in decision making, the authenticity and quality of the data is the most important factor in acquiring knowledge and ideas, so this is the most solid foundation for making successful decisions. However, the current business intelligence and data warehousing technologies do not fully support 4V theory, and the development of big data solutions addresses these challeng
