HaxMap is a fast, memory-efficient, lock-free concurrent hashmap library for Go, built on xxHash and Harris lock-free lists. It offers a generic key-value API with better performance than sync.Map and cornelk-hashmap in benchmarks.
Use cases
- fast concurrent key-value storage in go
- replace sync.Map with a faster hashmap
- thread-safe map with low memory allocations
- high-throughput concurrent reads and writes
- generic typed concurrent map for golang
When to choose
- you need maximum concurrent map performance in Go
- memory allocations per operation matter
- you want a generic, typed concurrent map API
When to avoid
- you need persistence or ordering guarantees
- your workload is single-threaded where a plain map suffices
- you need a distributed or sharded map across processes
