Incremental Updates

Rebuilding the whole corpus is not always necessary.

Update an existing graph

ts

const updated = await graphBuilder.updateGraph(previousResult, {
  upsert: [nextItem],
  deleteSourceItemIds: ["docs/old.md"]
});

Load a serialized graph

ts

const restored = graphBuilder.loadGraph(serializedResult);

When incremental mode helps

Source systems emit changed records one at a time.
You want short feedback loops in background sync jobs.
A user edits a subset of documents and you only need to refresh those source items.
