What you will learn

  • Explain idempotency, cache leases, data access, and cross-resource failure boundaries.
  • Review authorization, observability, configuration, and release assumptions with explicit test evidence.

  1. Queues and idempotent jobs

    Design deferred work around retries, durable business identity, and transaction boundaries instead of assuming a queue guarantees a single execution.

    Start learning

  2. Cache correctness and concurrency

    Treat cached data as a versioned, scoped derivative and choose freshness, invalidation, and lock behavior from the actual business contract.

    Start learning

  3. Query performance and indexes

    Investigate query count, returned data, and access paths using a declared workload instead of treating an index or eager loading as a universal speed guarantee.

    Start learning

  4. Secure file storage and authorized downloads

    Separate upload validation, private storage identity, access authorization, and download delivery so a convenient path never becomes a substitute for permission.

    Start learning

  5. Observability and failure handling

    Connect logs, metrics, and failure contracts to user-visible outcomes while protecting sensitive context and distinguishing liveness from dependency health.

    Start learning

  6. Deployment configuration and release safety

    Treat an application release as code plus resolved configuration and compatible long-running processes, with explicit verification and rollback limits.
