Caching

On this page

    When remote documents are fetched over HTTP, a Comunica engine can cache documents to optimize future reuse. If your application works over volatile resources, then you may want to invalidate this cache, which can be done as follows:

    // Invalidate the full cache
await myEngine.invalidateHttpCache();

// Invalidate a single document
await myEngine.invalidateHttpCache('http://example.org/page.html');

    Optionally, you can also pass the noCache: true flag to your context to invalidate the cache before query execution starts:

    const bindingsStream = await myEngine.queryBindings(`SELECT * WHERE { ?s ?p ?o }`, {
  sources: ['http://xmlns.com/foaf/spec/20140114.rdf'],
  noCache: true,
});
