As you can see from the boot in the Springboot project name, Springboot's role is to create and launch a new spring-based framework project. It is designed to help developers easily create spring-based frameworks for standalone runs and product-level applications. Springboot will choose the most appropriate spring sub-project and third-party open source Library for consolidation. Most springboot applications require very little configuration to run quickly. Springboot contains the following feat
under heavy load. These are issues that you cannot find during the development process as a single user through the test system. Early implementation of the Load Test Plan helps to minimize exceptions during development.
In this article, we will introduce the testing method based on practical experience, but this is not to leave the traditional load testing strategy behind. As we have led a large number of load testing teams, we have learned some lessons that may help you.
We will discuss the a

The buffer realization of transforming TELEGRAF
Objective
Recently, in a scenario that uses TELEGRAF, the data is not lost when the program terminates unexpectedly. According to the original implementation of TELEGRAF, two buffer was maintained inside the running_output, respectively metrics and failmetrics. These two buffer are based on the channel in Go. Because there

about to accomplish and the relevant optimization options. These goals need to be clear and concise, simple enough for the project manager to understand it, and you need to stick to those goals throughout the optimization process. In the software development process, the change is often the thing. You might want to optimize the goal at first, and then find that you need to optimize other goals. The same is true, but make a note of the changes to these goals.
