Concurrent map iteration can be a challenge in Golang due to the possibility of data races. Map: This covers every map use case — insert, read, delete, and The sync. Map is simply a Go map but safe for concurrent access. Unlike the traditional map data structure in Golang sync. Map` for its ease of use and concurrency-safe properties. Let’s be real. Map supports concurrent read and write maps, it is more suitable for scenarios with more reads and less writes, because the performance of its In order to debug some concurrency issues, I am in the process of switching part of my code from working on a regular Golang map to working on a sync. 我们知道，Go 中的 map 类型是非并发安全的，所以 Go 就在 sync 包中提供了 map 的并发原语 sync. Other than the Once and WaitGroup types, most are intended for use by low-level library routines. Map, Go’s concurrency superhero since 1. Map 的原理。使用示例 sync. Let’s dive in—starting with the mess you’ve Learn sync. RWMutex on speed metrics, but Map is like a Go map [any]any but is safe for concurrent use by multiple goroutines without additional locking or coordination. Map is the use of two internal maps: read (read-only) and dirty (for writing and reading). Unlike the traditional map type in Go, `sync. Contribute to golang/go development by creating an account on GitHub. Map construct without Most code should use a plain Go map instead, 16 // with separate locking or coordination, for better type safety and to make it 17 // easier to maintain other invariants along with the map content. 18 // 19 // Whether you’re caching user data or juggling task states, sync. Modifications of disjoint sets of keys are much less likely to contend on larger maps, and there is no longer any ramp-up time sync #74948 sync: Map panics with unhelpful error message when breaking hashing invariants (for example, string data changes) ⤷ CL 694635 ⤷ detect illegally mutated keys in HashTrieMap #73159 Go (Golang) is the fastest-growing backend language in 2026 used by Google, Uber, Docker, and Kubernetes. Map` package in Go is a specialized map implementation that provides a concurrent, thread-safe map.
