orchestration

DE//AGENT currently lists 8 resources under orchestration: 2 tutorials, 2 runbooks, 1 skill. Everything below is derived from the live registry — counts, capabilities, verification state and security posture come from the curated records, never from marketing copy.

Also present: 1 hook, 1 template, 1 reference.

Documented learning objectives across these resources:

• Scope a backfill by date and by dependency — via Backfill Planner
• Detect which downstream tables must also be rebuilt — via Backfill Planner
• Stage a backfill gradually with validation between batches — via Backfill Planner
• Name the four decisions orchestration makes — schedule, catchup, idempotency, backfill — via The orchestration mental model — DAGs, schedules, idempotency, backfills
• Apply the idempotency test to a task before running anything — via The orchestration mental model — DAGs, schedules, idempotency, backfills
• Say what a backfill is for and why it is dangerous — via The orchestration mental model — DAGs, schedules, idempotency, backfills
• Run the full four-step review pass end to end — via Capstone — the checklist that decides whether a DAG ships
• Confirm every checklist item on your own pipeline — via Capstone — the checklist that decides whether a DAG ships

1 more objectives live on the individual resource pages.

These resources map to stages: Orchestration (7), Reliability (1). Follow the four-phase roadmap to place this topic inside a progression instead of learning it in isolation.

Every entry, its shape and its trust state — sorted by the registry's composite score. This table is the honest version of a marketing comparison: no sponsored placements, no unverifiable claims.

How scores are computed: source quality score.

Highest composite score first:

1. Backfill Planner score 39.5 — advanced
2. The orchestration mental model — DAGs, schedules, idempotency, backfills score 34.15 — beginner
3. Capstone — the checklist that decides whether a DAG ships score 34.15 — intermediate

Scores rank provenance, completeness and trust — read how verification works before adopting anything.

Start here if you're new: The orchestration mental model — DAGs, schedules, idempotency, backfills, Pipeline failed.

Reach for these with production experience: Backfill Planner, Backfill Safety Check, Backfill required.

Security-flagged entries: Backfill Planner (1 flag), Backfill required (3 flags), Pipeline failed (4 flags), Airflow DAG Template (4 flags). Flags mean the record declares capabilities like credential use or write access — read the security posture on each page before connecting.

• Backfill Planner — Produces a backfill plan: date ranges, blast radius, resource contention, idempotency check, validation gates and rollback. details
• The orchestration mental model — DAGs, schedules, idempotency, backfills — Build the map before touching code: a DAG plus its schedule decides when runs happen, the idempotency test decides whether re-runs are safe, catchup decides what happens to missed … details
• Capstone — the checklist that decides whether a DAG ships — Close the series by running the full review pass over your own pipeline: the idempotency test per task, partitioned or MERGE writes, deliberate catchup, backoff retries, reschedule… details
• Backfill Safety Check — Refuse to start a backfill that lacks a rollback path or overlaps the daily run. details
