What are the best practices for using RWMutex in Go?

What are the best practices for using RWMutex in Go?

When using RWMutex in Go, it's important to minimize the time spent holding the lock. Use RLock for read operations and Lock for write operations.

Can you explain when to use RLock versus Lock?

Use RLock when multiple goroutines need to read shared data simultaneously, and Lock when a goroutine needs to write, ensuring exclusive access.

Are there any performance considerations I should be aware of?

Yes, excessive locking can lead to contention and performance bottlenecks. Always assess if RWMutex is necessary or if simpler synchronization methods would suffice.

What are some common mistakes to avoid with RWMutex?

Common mistakes include holding locks for too long, not releasing locks, and using RWMutex when a simpler solution would work.
