    Repair Cassandra Repair Anticompaction SSTable Leak

    Example session with this skill installed

    Case: A Cassandra node retains old SSTables after a successful repair pass.

    Provided: Cassandra repair session logs and SSTable lifecycle manifests (illustrative, partial). Potential exception: anticompaction references prevent obsolete segment cleanup. Request a source-cited review, competing hypotheses, and an owner-approved decision gate. Do not execute changes or assert unsupplied facts.

    Repair Cassandra Repair Anticompaction SSTable Leak — SYNTHETIC EVIDENCE-LIMITED REVIEW

    Case received

    A Cassandra node retains old SSTables after a successful repair pass.

    Evidence register

    • S1: Cassandra repair session logs and SSTable lifecycle manifests — 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 Cassandra repair session logs and SSTable lifecycle manifests; document missing or contradictory records. — PENDING CORROBORATION.
    2. Reconstruct the event sequence surrounding anticompaction references prevent obsolete segment cleanup, citing exact record identifiers and independent checks. — PENDING CORROBORATION.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A Cassandra node retains old SSTables after a successful repair pass. — PENDING CORROBORATION.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for non-destructive SSTable retention verification plan. — PENDING CORROBORATION.

    Deliverables

    • time-aligned evidence index for Cassandra repair session logs and SSTable lifecycle manifests: DRAFT / INCOMPLETE until inputs are validated.
    • exceptions and alternative hypotheses for anticompaction references prevent obsolete segment cleanup: DRAFT / INCOMPLETE until inputs are validated.
    • approval-gated non-destructive SSTable retention verification plan and verification criteria: DRAFT / INCOMPLETE until inputs are validated.

    About this skill

    Repair Cassandra Repair Anticompaction SSTable Leak is a ToolForge Labs Cursor Skill evidence-review workflow. Track unexpected disk growth after incremental repair sessions.

    What this skill checks

    1. Establish the identity, timestamp basis and revision lineage of Cassandra repair session logs and SSTable lifecycle manifests; document missing or contradictory records.
    2. Reconstruct the event sequence surrounding anticompaction references prevent obsolete segment cleanup, citing exact record identifiers and independent checks.
    3. Compare the evidence with the approved baseline; test the competing explanations for: A Cassandra node retains old SSTables after a successful repair pass.
    4. Draft a non-executing, owner-approved validation sequence and rejection criteria for non-destructive SSTable retention verification plan.

    What to provide

    • Cassandra repair session logs and SSTable lifecycle manifests
    • approved operating baseline / documented policy
    • timestamped revision or change record
    • accountable reviewer and approval evidence

    Deliverables

    • time-aligned evidence index for Cassandra repair session logs and SSTable lifecycle manifests.
    • exceptions and alternative hypotheses for anticompaction references prevent obsolete segment cleanup.
    • approval-gated non-destructive SSTable retention verification plan 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 specifically analyzes repair logs and SSTable manifests to identify why old files aren't being cleaned up after incremental repairs, preventing disk exhaustion. Unlike general tools, it correlates anticompaction timestamps with manifest deletions to pinpoint exactly where the cleanup routine failed.

    The skill is designed to work with Apache Cassandra logs and telemetry; it is compatible with major AI agents that support file uploads or text-based context, such as ChatGPT, Claude, and specialized developer assistants.

    No complex installation is required; simply provide the skill with your Cassandra repair session logs and SSTable lifecycle manifests to begin the automated reconstruction and analysis process.

    You receive the specialized AI agent skill configuration, a guide on extracting the necessary logs from your Cassandra environment, and access to future logic updates as new Cassandra versions are supported.

    This skill is an analysis and verification planning tool; it never directly executes commands or modifies your database, ensuring your production environment remains safe while you investigate.

    While optimized for standard Apache Cassandra incremental repair telemetry, it can also analyze logs from compatible distributions like DataStax Enterprise (DSE) that follow similar anticompaction and SSTable lifecycle patterns.
