# concurrent map [](https://circleci.com/gh/streamrail/concurrent-map)
|
||
|
|
|
||
|
|
As explained [here](http://golang.org/doc/faq#atomic_maps) and [here](http://blog.golang.org/go-maps-in-action), 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:
|
||
|
|
|
||
|
|
```go
|
||
|
|
import (
|
||
|
|
"github.com/streamrail/concurrent-map"
|
||
|
|
)
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
```bash
|
||
|
|
go get "github.com/streamrail/concurrent-map"
|
||
|
|
```
|
||
|
|
|
||
|
|
The package is now imported under the "cmap" namespace.
|
||
|
|
|
||
|
|
## example
|
||
|
|
|
||
|
|
```go
|
||
|
|
|
||
|
|
// 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")
|
||
|
|
|
||
|
|
```
|
||
|
|
|
||
|
|
