Quick Reference
Go Concurrency: Goroutines are cheap (2KB), spawn freely. Channels for communication, not shared memory. Close channels only from sender. Context for cancellation/timeouts. Worker pools for bounded concurrency. select for multiplexing. errgroup for error propagation. Always handle goroutine lifecycle. Test with -race flag.
Use When
- Concurrent Go applications
- Parallel data processing
- Network servers
- Background workers
Skip When
- Simple sequential programs
- Single-threaded requirements
- CPU-bound without parallelism benefit
