We need to lock it to prevent other routines/thread to change the value while we process it. Web func (c *container) inc(name string) {. Web a mutex is a method used as a locking mechanism to ensure that only one goroutine is accessing the critical section of code at any point of time. Web by lane wagner on mar 19, 2020 golang is king as it comes until concurrency. The default go implementation of sync.rwmutex does not scale well to multiple cores, as all readers contend on the same memory location. Web if you need to read from and write to a map from concurrently executing goroutines, the accesses must be mediated by some kind of synchronization. I need a read preferring rw mutex in golang. The default value is an unlocked mutex, as you can see from the standard library code: Maps are safe for concurrent read access, just not concurrent read/write or write/write access. Web rwmutex — safely allow multiple readers.
A mutex is used to provide a locking mechanism to ensure that only one goroutine is running the critical section of code at any point in time to prevent race.

Web rwmutex — safely allow multiple readers. Is there a package in golang that will satisfy my needs. The read method calls the sync.rlock() and sync.runlock(). We need to lock it to prevent other routines/thread to change the value while we process it. I tried sync.rwmutex, but it seems to be write. Rwmutex is a slightly more complicated primitive:
