concurrent map

As explained here and here, the map type in Go doesn't support concurrent reads and writes. concurrent-map provides a high-performance solution to this by sharding the map with minimal time spent waiting for locks.

usage

Import the package:

import (
	"github.com/streamrail/concurrent-map"
)

go get "github.com/streamrail/concurrent-map"

The package is now imported under the "cmap" namespace.

example

	// Create a new map.
	map := cmap.New()
	
	// Sets item within map, sets "bar" under key "foo"
	map.Set("foo", "bar")

	// Retrieve item from map.
	if tmp, ok := map.Get("foo"); ok {
		bar := tmp.(string)
	}

	// Removes item under key "foo"
	map.Remove("foo")

Running tests:

go test "github.com/streamrail/concurrent-map"
