    Repair ClickHouse Keeper Watch Session Expiry

    Example session with this skill installed

    Case: ClickHouse replicas disagree about metadata updates after network recovery.

    Provided: ClickHouse Keeper watch delivery logs and replica session epochs (illustrative, partial). Potential exception: watch registration remains bound to an expired coordination session. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair ClickHouse Keeper Watch Session Expiry — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    ClickHouse replicas disagree about metadata updates after network recovery.

    Evidence register

    • S1: ClickHouse Keeper watch delivery logs and replica session epochs — 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 ClickHouse Keeper watch delivery logs and replica session epochs; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding watch registration remains bound to an expired coordination session, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: ClickHouse replicas disagree about metadata updates after network recovery. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for database owner keeper watch resubscription fixture and replica convergence review. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for ClickHouse Keeper watch delivery logs and replica session epochs: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for watch registration remains bound to an expired coordination session: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated database owner keeper watch resubscription fixture and replica convergence review and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    What to provide

    • ClickHouse Keeper watch delivery logs and replica session epochs
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for ClickHouse Keeper watch delivery logs and replica session epochs.
    • exceptions and alternative hypotheses for watch registration remains bound to an expired coordination session.
    • approval-gated database owner keeper watch resubscription fixture and replica convergence 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 identifies why replicas fail to update after network events by correlating ClickHouse Keeper logs with session epochs to find 'stuck' watches and expired session handles.

    It is designed to work with any LLM-based agent capable of processing structured logs and time-series data, such as those built on AutoGen, LangChain, or CrewAI.

    You will receive the specialized investigation framework, the logic for log-to-epoch correlation, and templates for generating convergence validation fixtures.

    Yes, this skill is fully compatible with both native ClickHouse Keeper and legacy ZooKeeper setups, provided you can supply the relevant coordination logs.

    No, this is an analytical diagnostic tool; it generates the evidence and repair scripts you need, but it does not directly modify your database or keeper state.

    You should provide ClickHouse server logs from affected replicas and the coordination logs (Keeper/ZooKeeper) covering the period of the network event or desynchronization.
