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
