+A sink contains five functions and is derived from the type `sink`:
+* `Init(name string, config json.RawMessage) error`
 * `Write(point CCMetric) error`
 * `Flush() error`
 * `Close()`
+* `New<Typename>(name string, config json.RawMessage) (Sink, error)` (calls the `Init()` function)
 
 The data structures should be set up in `Init()` like opening a file or server connection. The `Write()` function writes/sends the data. For non-blocking sinks, the `Flush()` method tells the sink to drain its internal buffers. The `Close()` function should tear down anything created in `Init()`.
