    Repair CockroachDB Changefeed Resolved Timestamp Lag

    Example session with this skill installed

    Case: A changefeed publishes rows but leaves checkpoint progress indefinitely stale.

    Provided: CockroachDB changefeed job metrics and resolved timestamp traces (illustrative, partial). Potential exception: resolved timestamp stalls behind an abandoned span checkpoint. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair CockroachDB Changefeed Resolved Timestamp Lag — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A changefeed publishes rows but leaves checkpoint progress indefinitely stale.

    Evidence register

    • S1: CockroachDB changefeed job metrics and resolved timestamp 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 CockroachDB changefeed job metrics and resolved timestamp traces; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding resolved timestamp stalls behind an abandoned span checkpoint, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A changefeed publishes rows but leaves checkpoint progress indefinitely stale. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for non-destructive checkpoint recovery acceptance cases. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for CockroachDB changefeed job metrics and resolved timestamp traces: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for resolved timestamp stalls behind an abandoned span checkpoint: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated non-destructive checkpoint recovery acceptance cases and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    Repair CockroachDB Changefeed Resolved Timestamp Lag is a ToolForge Labs ChatGPT Skill evidence-review workflow. Investigate changefeed consumers stuck behind resolved timestamp barriers.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of CockroachDB changefeed job metrics and resolved timestamp traces; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding resolved timestamp stalls behind an abandoned span checkpoint, citing exact record identifiers and independent checks.

    What to provide

    • CockroachDB changefeed job metrics and resolved timestamp traces
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for CockroachDB changefeed job metrics and resolved timestamp traces.
    • exceptions and alternative hypotheses for resolved timestamp stalls behind an abandoned span checkpoint.
    • approval-gated non-destructive checkpoint recovery acceptance cases 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.

    Find more skills like this on the Claude Skills Marketplace, the Codex Skills Marketplace and the Gemini Skills Marketplace, or browse Claude Skills for Data & Databases.

    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.

    Frequently Asked Questions

    This skill provides a structured, evidence-based framework to diagnose why a CockroachDB changefeed high-water mark has stopped advancing, specifically focusing on identifying abandoned span checkpoints and stale progress markers without risking data loss.

    You will need to provide job metrics, resolved timestamp traces, and specific record identifiers; the skill then processes this data to reconstruct the event sequence and isolate the root cause of the lag.

    No, this skill is designed for safety and does not execute database commands; instead, it generates a non-destructive recovery plan and evidence log for an SRE to review and execute manually.

    This skill is optimized for CockroachDB (CRDB) operators and SREs using AI agents capable of processing structured logs and performance metrics, such as ChatGPT, Claude, or specialized developer environments.

    The purchase includes the complete investigation framework, including metric analysis templates, hypothesis testing protocols, and a structured format for generating human-gated recovery plans.
