title: Relay Pagination - Remove old nodes from store after cursor changed
body: <p>I implemented pagination system by using <a href="https://relay.dev/docs/en/pagination-container" rel="nofollow noreferrer">pagination container</a>. It works great with one problem.</p>
  <p>When i call loadMore function to get new nodes relay fetches nodes from server and adds to olds ones. But i want to delete old nodes and just want to show new ones.</p>
  <p>For example $first = 10</p>
  <p>When the page first loads i got 10 nodes, after loadMore i get 20 nodes. But i want to show just new fetched 10 nodes.</p>
  <p>I used this <a href="https://relay.dev/docs/en/pagination-container#pagination-example" rel="nofollow noreferrer">pagination example</a></p>
  <p>I could not find a way to remove old nodes after loadMore action.</p>
  <p>I know relay pagination intended to use only infinite scroll, i just wonder maybe there is a way to solve this problem.</p>
