3 years ago How about using a plane map + RWMutex ?
The Map type is specialized. Most code should use a plain Go map instead,
with separate locking or coordination, for better type safety and to make it easier to maintain other invariants along with the map content.
The Map type is optimized for two common use cases:
(1) when the entry for a given key is only ever written once but read many times, as in caches that only grow,
or (2) when multiple goroutines read, write, and overwrite entries for disjoint sets of keys.
In these two cases, use of a Map may significantly reduce lock contention compared to a Go map paired with a separate Mutex or RWMutex.
