What you will learn

  • Evaluate explain metrics, concerns and routing from evidence.
  • Design historical recovery, stream processing and compatible releases.

  1. Explain plans and workload performance

    Investigate query work, selectivity and contention without treating an index name or one timing sample as proof. Read MongoDB explain results in their version context.

    Start learning

  2. Replica sets and read/write concerns

    Separate routing preference, durability acknowledgment and read visibility. Reason about elections, replication lag and causal sessions without promising universal zero-loss behavior.

    Start learning

  3. Sharding and routing design

    Choose shard keys from distribution, query targeting and lifecycle requirements. Understand scatter/gather work, unique-index scope and the cost of moving data.

  4. Backup, recovery and restore evidence

    Choose recoverable artifacts from loss and recovery-time requirements. Distinguish self-managed tools, consistent snapshots and Atlas backup capabilities without inventing universal guarantees.

  5. Windows, change streams and maintained results

    Compute per-document analytics and design resumable change processing without promising automatic exactly-once external effects. Bound pipelines and derived-result maintenance.

  6. Operations, evolution and release reliability

    Plan MongoDB changes as compatible, observable and recoverable transitions. Coordinate schema, indexes, feature compatibility, drivers and write ownership.
