# Watch 

###
Companion object Watch

#### class Watch[T] extends AnyRef

Watches are a way of specifying a view of data (e.g. list of nodes, KV pairs, health checks) which is monitored for updates. When an update is detected, an `Handler` with `WatchResult` is invoked. All errors, except `java.util.concurrent.TimeoutException`, will be handled, with resubscribing with a progressive delay. All timeout errors will be ignored, with resubscribing without any delay. As an example, you could watch the status of health checks and notify when a check is critical.
