How Can I Prevent Concurrent Map Write Crashes in Go?

Preventing Concurrent Map Write Crashes

When attempting to concurrently write to the same map from multiple goroutines, Go 1.6 triggers a deliberate crash to prevent data corruption. Unlike panics that can be recovered from using defer and recover, this crash is intentional and cannot be intercepted.

To resolve this issue, avoid concurrent writes to maps. In the provided example:

The concurrent writes to the map from multiple goroutines violate Go's concurrency rules for maps, causing the intentional crash.

To prevent this crash and enforce data integrity, consider using a mutex or synchronization primitive to control access to the map. This ensures that only one goroutine can modify the map at a time.
