2013. 11. 17. &0183;&32;orcaman current go sync.Map can be faster or slower than hash-sharded even in your append-only case. It really depends on the scenario. Using as much atomic operations as possible, the sync.Map internals can be much faster than traditional sharding since it minimize locking versus traditional hash-bucket but required locking. Nov 26, 2021 Writing With a Synchronized Map. Because concurrent goroutines are used so commonly in Go, the standard library has a specialized data structure that acts like a normal map, but is perfectly safe to be read and written to across multiple goroutines without the use of an external mutex. The sync.Map type stores keys and values of any type (using ..
After go1.9, a safe map object has been added to the sync package. syn.Map does not support normal map operations and needs to use the api provided by sync.Map. Create sync.Map object. 1. It does not need to be created by map,. Golang Maps is a compilation of unordered key-value pairs.

Dec 03, 2016 &183; The actual details of such a map are a bit subtle to implement correctly and efficiently. We should provide a Map implementation in the standard library. Since the implementation may need to use both sync and syncatomic and the former depends on the latter, it should either go in sync or in a new, separate sync subpackage.
