    Repair Kafka Tiered Fetch Epoch Mismatch

    Example session with this skill installed

    Case: Kafka read requests intermittently fail after moving segments to object storage.

    Provided: tiered storage fetch logs and partition leader epoch history (illustrative, partial). Potential exception: remote segment metadata retains an obsolete leader epoch after reassignment. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Kafka Tiered Fetch Epoch Mismatch — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    Kafka read requests intermittently fail after moving segments to object storage.

    Evidence register

    • S1: tiered storage fetch logs and partition leader epoch history — 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

    1. Establish the identity, timestamp basis and revision lineage of tiered storage fetch logs and partition leader epoch history; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding remote segment metadata retains an obsolete leader epoch after reassignment, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: Kafka read requests intermittently fail after moving segments to object storage. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for streaming owner remote fetch boundary fixture and replay safety review. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for tiered storage fetch logs and partition leader epoch history: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for remote segment metadata retains an obsolete leader epoch after reassignment: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated streaming owner remote fetch boundary fixture and replay safety review and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    INCOMPLETE — HUMAN REVIEW REQUIRED. Sources, scope, time basis and sign-off remain unverified. No live change or approval has occurred.

    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for tiered storage fetch logs and partition leader epoch history.
    • exceptions and alternative hypotheses for remote segment metadata retains an obsolete leader epoch after reassignment.
    • approval-gated streaming owner remote fetch boundary fixture and replay safety review and verification criteria.

    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.

    Frequently Asked Questions

    This skill automates the complex task of correlating Kafka fetch logs with leader epoch history to identify why tiered storage requests are failing, specifically targeting errors caused by stale metadata in remote object stores.

    Yes, it is compatible with any environment utilizing Kafka Tiered Storage (KIP-405) and major cloud providers including AWS S3, Google Cloud Storage, and Azure Blob Storage.

    The skill is designed to be imported into any LLM-based agent or platform that supports structured file inputs, such as ChatGPT, Claude, or custom enterprise AI orchestration tools.

    No, this is a diagnostic and investigative tool that generates evidence-based reports and validation criteria; it does not execute API calls or configuration changes in your live production cluster.

    You receive the full skill logic, a structured investigative framework, and a guide on the specific log formats and telemetry data required to produce accurate results.

    This skill provides a rigorous 'evidence-based' framework that categorizes findings as VERIFIED or UNVERIFIED, preventing the hallucinated root causes that often occur with standard, unstructured prompts.
