What Is a Data Backfill?
A data backfill is the process of loading data for past time periods or previously missing rows into a table or system that did not capture it originally. It is run after introducing a new field, dataset, or pipeline that needs history. Backfills are usually batched and throttled to avoid overwhelming the live system.
Why it matters
New analytics or features often need history that was never recorded, and a backfill supplies it. Latchkey runs backfill jobs in its worker tier to load past CI run data so dashboards show a complete timeline.
