<p>To make the replication work, and for other reasons, RxDB has to keep deleted documents in the storage so that it is able to replication the deletion state of documents.
This ensures that when a client is offline, the deletion state is still known and can be replicated with the backend when the client goes online again.</p>
<p>Keeping too many deleted documents in the storage, can slow down queries or fill up too much disc space.
With the cleanup plugin, RxDB will run cleanup cycles that clean up deleted documents when it can be done safely.</p>

<p>When you have a collection with documents and you want to empty it by purging all documents, the recommended way is to call <code>myRxCollection.remove()</code>. However this will destroy the JavaScript class of the collection and stop all listeners and observables.
Sometimes the better option might be to manually delete all documents and then use the cleanup plugin to purge the deleted documents:</p>

For example by default the cleanup does not run in the first 60 seconds of a collections creation to ensure an initial page load of your website will not be slowed down. Also we use mechanisms like the <code>requestIdleCallback()</code> API to improve the correct timing of the cleanup cycle.</p></div></div></div></details></div></article><nav class="pagination-nav docusaurus-mt-lg" aria-label="Docs pages"><a class="pagination-nav__link pagination-nav__link--prev" href="/rx-local-document.html"><div class="pagination-nav__sublabel">Previous</div><div class="pagination-nav__label">Local Documents</div></a><a class="pagination-nav__link pagination-nav__link--next" href="/backup.html"><div class="pagination-nav__sublabel">Next</div><div class="pagination-nav__label">Backup</div></a></nav></div></div><div class="col col--3"><div class="tableOfContents_bqdL thin-scrollbar theme-doc-toc-desktop"><ul class="table-of-contents table-of-contents__left-border"><li><a href="#installation" class="table-of-contents__link toc-highlight">Installation</a></li><li><a href="#create-a-database-with-cleanup-options" class="table-of-contents__link toc-highlight">Create a database with cleanup options</a></li><li><a href="#calling-cleanup-manually" class="table-of-contents__link toc-highlight">Calling cleanup manually</a></li><li><a href="#using-the-cleanup-plugin-to-empty-a-collection" class="table-of-contents__link toc-highlight">Using the cleanup plugin to empty a collection</a></li><li><a href="#faq" class="table-of-contents__link toc-highlight">FAQ</a></li></ul></div></div></div></div></main></div></div></div><div class="block footer"><div class="footer-block"><div class="footer-links"><span><a variant="text" href="/" class="footer-logo-button"><img src="/files/logo/logo.svg" alt="RxDB" loading="lazy"><div>RxDB</div></a><div class="footer-community-links"><a variant="text" href="/chat/" target="_blank"><img src="/img/community-links/discord-logo.svg" alt="RxDB Discord" loading="lazy"></a><a variant="text" href="/code/" target="_blank"><img src="/img/community-links/github-logo.svg" alt="RxDB Github" loading="lazy"></a><a variant="text" href="https://twitter.com/intent/user?screen_name=rxdbjs" target="_blank"><img src="/img/community-links/x-logo.svg" alt="RxDB Twitter" loading="lazy"></a><a variant="text" href="https://www.linkedin.com/company/rxdb" target="_blank"><img src="/img/community-links/linkedin-logo.svg" alt="RxDB LinkedIn" loading="lazy"></a><a variant="text" href="https://stackoverflow.com/questions/tagged/rxdb" target="_blank"><img src="/img/community-links/stack-overflow-logo.svg" alt="RxDB Stack Overflow" loading="lazy"></a></div></span><div class="footer-nav-links"><a variant="text" href="/premium/" target="">Premium</a><a variant="text" href="/consulting/" target="">Support</a><a variant="text" href="/overview.html" target="">Documentation</a><a variant="text" href="/chat/" target="_blank">Discord</a><a variant="text" href="/code/" target="_blank">Github</a><a variant="text" href="https://twitter.com/intent/user?screen_name=rxdbjs" target="_blank">Twitter</a><a variant="text" href="https://www.linkedin.com/company/rxdb" target="_blank">LinkedIn</a></div></div><div class="footer-policy"><div><a variant="text" href="/legal-notice/" target="_blank">Legal Notice</a></div><span class="footer-rights">© 2025 RxDB.
