    Repair Read Replica Consistency

    Example session with this skill installed

    Our users see old profile data right after saving changes. We use a Rails app with a Postgres primary and two replicas. Can you fix this stale read issue?

    • Read your context and instructions
    • Compiled the repair read replica

    I have analyzed your ApplicationController and identified missing session-stickiness for writes. I updated the database configuration to use 'distributes_reads' with a 2-second primary fallback window and added a test case simulating replica lag to verify the fix.

    About this skill

    Repair stale reads when apps write to a primary database but immediately read from lagging replicas.

    This skill traces database routing, consistency boundaries, and failover behavior. It adds read-your-writes guarantees, lag-aware routing, bounded primary fallback, monotonic reads, and replica-focused tests.

    • Prevent post-save stale screens
    • Protect critical workflows
    • Detect replica lag
    • Verify failover and recovery

    Ideal for SaaS, APIs, dashboards, and distributed databases.

    • Cannot fix physical network latency between regions.
    • Limited by the underlying database driver capabilities.
    • Requires existing test suites for safest validation.

    Frequently Asked Questions

    It prefers scoped consistency like session-based routing or read-your-writes markers over sending all traffic to the primary database.

    Yes, it can trace issues to caching layers or search indexes if they are part of the stale read path.

    It uses Bash to run safe builds and tests, including simulated lag to verify that consistency logic works before deployment.
