polling.js

class Polling extends React.Component {
  componentDidMount() {
    this.intervalId = setInterval(this.props.callback, this.props.interval);
  }

  componentWillUnmount() {
    clearInterval(this.intervalId);
  }

  render() {
    return this.props.children;
  }
}

Perhaps you could use that something like this:

const PollingQuery = ({ interval, children, ...queryProps }) => (
  <Query {...queryProps}>
    {queryRenderArgs => (
      <Polling interval={interval} callback={queryRenderArgs.load}>
        {children(queryRenderArgs)}
      </Polling>
    )}
  </Query>
)

I'm pretty sure that loads of the same query that is in flight await the inflight request instead of sending a new request. So it should be safe to aggressively poll?

That looks good
