Golang Concurrent Map Iteration And Map Write Example of how Golang generics minimize the amount of code you need to write I guess that almost everyone in the go community was exciting when Go 1 18 was released especially because of generics Some days ago I decided to try generics in the real world application by refactoring some of its pieces related to a caching logic
Mastering Concurrency in Golang Goroutines Channels and Synchronization Concurrency is one of Golang s standout features making it the go to language for developers building high performance Q How do I iterate over a concurrent map in Golang A There are two ways to iterate over a concurrent map in Golang The first way is to use the range keyword When used with a concurrent map the range keyword will iterate over the map s keys in a lock free manner The second way to iterate over a concurrent map is to use the sync Map

With such a change the global instance of RuleEngineService is locked appropriately when calling Evaluate enforcing the correct order of read write operations and thus preventing concurrent map write errors Another contributing factor towards our identified issue relates to the client code s usage of RuleEngineService Golang is known for its concurrency support but accessing maps concurrently can lead to unexpected panics In this article we ll dive into the reasons behind the restriction on concurrent read
In GoLang Map is unordered pair of key value provides fastest lookup and operation on Data you can also Iterate over Maps It is most widely used InMemory Data Structure for Golang Based Iterate using m Range which safely iterates through keys and values within the map Benefits and Limitations of sync Map sync Map is particularly suitable for cases where frequent concurrent reads and writes occur but it is important to consider some trade offs Supports concurrent access by design without additional locking mechanisms

Runtime concurrent map access detection in hashmap go only catches one stack 26703 runtime race document and fix trap when race detected 23577 runtime crash while deleting all keys in map while ranging over it with Go 1 1 2 6216 Emoji vote if this was helpful or unhelpful more detailed feedback welcome in this discussion hardik cisco does go vet report any issues for your code The two lines reported in the race are A write in Store A read in Range The write is to the dirty map guarded by m mu The read is from the readOnly map The dirty map can be promoted to the readOnly map in these places Range with m mu locked missLocked with m mu presumed to be locked by the caller
