Repair Apache Flink Serializer UID Compatibility Gap
Example session with this skill installed
Case: Flink savepoint restore fails for one keyed aggregation operator.
Provided: Flink savepoint metadata and keyed state serializer version records (illustrative, partial). Potential exception: operator UID mapping changes without matching serializer snapshot migration. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

Repair Apache Flink Serializer UID Compatibility Gap — SYNTHETIC EVIDENCE-LIMITED REVIEW
Case received
Flink savepoint restore fails for one keyed aggregation operator.
Evidence register
- S1: Flink savepoint metadata and keyed state serializer version records — PARTIAL / UNVERIFIED.
- S2: approved operating baseline / documented policy — NOT PROVIDED; REQUIRED TO VERIFY.
- S3: timestamped revision or change record — NOT PROVIDED; REQUIRED TO VERIFY.
- S4: accountable reviewer and approval evidence — NOT PROVIDED; REQUIRED TO VERIFY.
Investigation checks
- Establish the identity, timestamp basis and revision lineage of Flink savepoint metadata and keyed state serializer version records; document missing or contradictory records. — PENDING CORROBORATION.
- Reconstruct the event sequence surrounding operator UID mapping changes without matching serializer snapshot migration, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
- Compare the evidence with the approved baseline; test the competing explanations for: Flink savepoint restore fails for one keyed aggregation operator. — PENDING CORROBORATION.
- Draft a non-executing, owner-approved validation sequence and rejection criteria for stream owner savepoint compatibility fixture and rollback plan. — PENDING CORROBORATION.
Deliverables
- time-aligned evidence index for Flink savepoint metadata and keyed state serializer version records: DRAFT / INCOMPLETE until inputs are validated.
- exceptions and alternative hypotheses for operator UID mapping changes without matching serializer snapshot migration: DRAFT / INCOMPLETE until inputs are validated.
- approval-gated stream owner savepoint compatibility fixture and rollback plan and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

Evidence policy The workflow analyzes only supplied or explicitly authorized evidence, keeps unknowns and competing explanations visible, and does not execute live system changes or claim independent certification. An authorized owner must approve operational decisions.

No live validation or direct platform access is asserted. Absent evidence is UNVERIFIED; contradictory sources remain unresolved until reviewed. Only authorized owners may approve real-world actions.
