Original link: https://colobu.com/2022/09/01/fizzbuzz-in-go/ Today, a classmate gave me a concurrent question. As the author of “GO Concurrent Programming Practical Course” in geek time, I didn’t answer it for a while. I am ashamed, so I studied the topic in the evening and gave some tips. Implementation options are discussed. This question seems to have been …
Original link: https://colobu.com/2022/08/30/waitgroup-to-love-to-toss/ WaitGroup is a concurrency primitive that is often used in Go concurrent programming for task scheduling. It looks like it has only a few simple methods and is relatively simple to use. In fact, the internal implementation of WaitGroup has also changed several times, mainly to optimize the atomic operation of its …

This article records several important optimization points for your reference. Add handler method to avoid using reflect on the server In the previous rpcx implementation, the reference is to the registration method of the standard …

Original link: https://colobu.com/2022/07/31/2022-rpc-frameworks-benchmarks/ It has been a whole year since the last test of the Go ecosystem rpc framework benchmark in 2021 . In the past year, various RPC frameworks have also made great progress, and rpcx has also made some beneficial optimizations and simplifications with the support of many netizens, so it is time …

Original link: https://colobu.com/2022/05/22/use-ebpf-to-trace-rpcx-microservices/ ebpf is an innovative and revolutionary technology that can run sandboxed programs in the kernel without modifying the kernel source code or loading kernel modules. Making the Linux kernel programmable enables smarter, more feature-rich infrastructure software to build on existing (rather than adding new) abstraction layers without increasing system complexity or sacrificing …
