# Smart Subscription
Each subscription declared in the `apollo.$subscribe` option in a component results in the creation of a smart subscription object.
## Options
- `query`: GraphQL document (can be a file or a `gql` string).
- `variables`: Object or reactive function that returns an object. Each key will be mapped with a `'$'` in the GraphQL document, for example `foo` will become `$foo`.
- `throttle`: throttle variables updates (in ms).
- `debounce`: debounce variables updates (in ms).
- `result(data)` is a hook called when a result is received
## Properties
### Skip
You can pause or unpause with `skip`:
```js
this.$apollo.subscriptions.users.skip = true
```
## Methods
### refresh
Stops and restarts the query:
```js
this.$apollo.subscriptions.users.restart()
```
### start
Starts the query:
```js
this.$apollo.subscriptions.users.start()
```
### stop
Stops the query:
```js
this.$apollo.subscriptions.users.stop()
```
