    Repair Kafka KRaft Controller Epoch Watch Staleness

    Example session with this skill installed

    Case: A producer receives obsolete partition leadership after a clean controller swap.

    Provided: Kafka KRaft metadata log and controller epoch follower traces (illustrative, partial). Potential exception: controller watch cursor lags the newly committed metadata epoch. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Kafka KRaft Controller Epoch Watch Staleness — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A producer receives obsolete partition leadership after a clean controller swap.

    Evidence register

    • S1: Kafka KRaft metadata log and controller epoch follower traces — 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 Kafka KRaft metadata log and controller epoch follower traces; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding controller watch cursor lags the newly committed metadata epoch, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A producer receives obsolete partition leadership after a clean controller swap. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for metadata observer recovery and leader epoch regression suite. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Kafka KRaft metadata log and controller epoch follower traces: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for controller watch cursor lags the newly committed metadata epoch: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated metadata observer recovery and leader epoch regression suite and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    Decision gate

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

    What to provide

    • Kafka KRaft metadata log and controller epoch follower traces
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Kafka KRaft metadata log and controller epoch follower traces.
    • exceptions and alternative hypotheses for controller watch cursor lags the newly committed metadata epoch.
    • approval-gated metadata observer recovery and leader epoch regression suite 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 provides a structured diagnostic framework to identify why Kafka KRaft metadata observers fall behind during controller rotations, causing producers to receive outdated partition leadership data.

    The skill requires you to provide Kafka metadata logs, epoch follower traces, and partition leadership change records from the period surrounding the controller swap.

    No, this skill is designed for offline root-cause analysis and does not have the capability to execute commands or make live configuration changes to your production Kafka cluster.

    This skill is optimized for AI agents capable of complex logical reasoning and is compatible with most major LLMs that support large-context log analysis.

    You receive the specialized investigative logic, the hypothesis testing framework, and a structured template for generating recovery and regression sequences.

    Yes, as Kafka's KRaft implementation evolves, the skill is updated to reflect new metadata record types and documented edge cases in controller epoch management.
