Effective competitive programming patterns in Golang

The article discusses effective competitive programming patterns in the Go language, designed to develop high-performance and reliable multithreaded applications. The key competitive mechanisms in Go are analyzed, including goroutines, channels, and synchronization primitives. Popular patterns such as Worker Pool, Fan-out/Fan-in, Pipeline, Pub/Sub, Barrier, Throttling, and Circuit Breaker are reviewed, with an assessment of their advantages, disadvantages, and applications. Based on the comparative analysis, recommendations are given on the choice of optimal approaches for various scenarios. Special attention is paid to typical errors (data races, deadlocks, memory leaks) and ways to prevent them. The results of the study may be useful to developers seeking to improve the efficiency and stability of competitive applications on Google.
