Preserving Order in Concurrent Go Apps: Three Approaches Compared
Concurrency is one of Go’s greatest strengths, but it comes with a fundamental trade-off: when multiple goroutines process data simultaneously, the natural ordering gets scrambled. Most of the time, this is fine – unordered processing is enough, it’s faster and simpler. But sometimes, order matters. When Order Matters Here are three real-world scenarios where preserving order becomes critical: Real-time Log Enrichment: You’re processing a high-volume log stream, enriching each entry with use
