Repair Snowflake Task Dependency Missed Run

Repair Snowflake Task Dependency Missed Run — EVIDENCE-LIMITED REVIEW

Scenario received

An overnight Snowflake transformation is skipped after an upstream task resumes late.

Evidence inventory

• S1: task DDL definitions — partial extract described by the requester; original full source not provided here.
• S2: task history records — partial extract described by the requester; original full source not provided here.
• S3: warehouse suspend events — NOT PROVIDED; required to validate dependent findings.
• S4: dependency graph versions — NOT PROVIDED; required to validate dependent findings.

Case-specific checks

Rebuild predecessor graph. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
2.

Compare scheduler and warehouse status. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
3.

Identify failure propagation. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.
4.

Test catch up logic without duplicate loads. INCOMPLETE until matching source anchors can be examined; document the observable facts, counterexamples and decision gate.

Deliverables

Missed run dependency map. Create an evidence-linked section with observations, missing data, owner and next validation step.

Task graph correction. Create an evidence-linked section with observations, missing data, owner and next validation step.

Catch up validation steps. Create an evidence-linked section with observations, missing data, owner and next validation step.

Acceptance gate

Recovery prevents duplicate ingestion and records which intervals remain unverified. Do not label this gate passed until supplied source records actually demonstrate it.

Verdict and next action

INCOMPLETE — evidence required. Request S3 and S4 from the authorized owner, reconcile them with S1 and S2, then repeat the four checks and log remaining conflicts. No production change, approval, communication, or test run is claimed.
