Workflow

  • Define correctness criteria for the backfill.
  • Compute downstream impact from lineage.
  • Estimate cost and contention.
  • Stage batches with validation between them.

Inputs

  • Target table and date range
  • Pipeline dependencies and lineage

Outputs

  • Impact set
  • Batched execution plan
  • Validation gates
  • Rollback procedure

Guardrails

  • Refuses to plan without a rollback path
  • Requires an explicit window with the daily job excluded

Example

Plans a 90-day backfill around the 01:00 daily run, batched weekly, with a shadow table and a row-count gate.

Evaluation

Plans validated against known-good backfill runbooks.
