Pull on installation

When a data source is first connected, Virgo pulls its existing history, not just new activity. This backfill means the graph reflects the work that already happened, so retrieval is useful from the start instead of only after weeks of new data.

What the backfill does

Virgo reads the source’s records, runs them through ingestion (extract, canonicalize, link), and places the resulting entities and relationships in the graph. Historic work becomes queryable alongside everything captured afterward.

After the backfill

Once history is loaded, Virgo keeps the source current. Sources that support webhooks update in real time; the rest are polled on a schedule.
