This [REST Layer](https://github.com/rs/rest-layer) resource storage wrapper uses [hystrix-go](github.com/afex/hystrix-go) to add circuit breaker support to any REST Layer resource storage handler.

## Usage

```go

import "github.com/rs/rest-layer-hystrix"

```

Wrap existing storage handler with a name that will be used to construct hystrix commands:

```go

s := restrix.Wrap("myResource", mem.NewHandler())

```

Use this handler with a resource:

```go

index.Bind("foo", foo, s, resource.DefaultConf)

```

Customize the hystrix commands:

```go

// Configure hystrix commands

hystrix.Configure(map[string]hystrix.CommandConfig{

    "posts.Find": {

        Timeout:               1000,

        MaxConcurrentRequests: 100,

        ErrorPercentThreshold: 25,

    },

    "posts.Insert": {

        Timeout:               1000,

        MaxConcurrentRequests: 50,

        ErrorPercentThreshold: 25,

    },

    ...

})

```

Start the metrics stream handler:

```go

hystrixStreamHandler := hystrix.NewStreamHandler()

hystrixStreamHandler.Start()

log.Print("Serving Hystrix metrics on http://localhost:8081")

go http.ListenAndServe(net.JoinHostPort("", "8081"), hystrixStreamHandler)

```
