Reference and Selective Reading

This generated surface maps a learner-facing curriculum unit to its canonical source routes.

Curriculum surface​

  • Open learner-facing unit
  • Curriculum path: content/curriculum/architecture/semester-06-databases-distributed/module-03-replication-partitioning/reference/index.md
  • App: architecture
  • Semester: semester-06-databases-distributed
  • Module: module-03-replication-partitioning
  • Unit kind: reference
  • Curation level: module_curated

Learning objectives​

  • Explain Reference and Selective Reading in terms of topology, failure handling, and scaling tradeoffs instead of feature lists.
  • Use Reference and Selective Reading to predict what breaks or changes when data is copied, partitioned, or rebalanced across nodes.
  • Use database-internals, database-system-concepts, ddia, distributed-systems-concepts-and-design to connect the learner page to lag, routing, quorums, hotspots, and operational reality.

Prerequisites​

  • Comfort with storage-engine basics, indexing, and single-node database tradeoffs from the earlier modules.

Source books​

  • database-internals
  • database-system-concepts
  • ddia
  • distributed-systems-concepts-and-design

External enrichment​

  • PostgreSQL Documentation: Replication (official_docs_companion) - Useful when the learner needs an implementation-backed view of leader/follower replication and lag-related tradeoffs.
  • Jepsen Analyses (optional_deep_dive) - Provides concrete failure stories that sharpen the learner’s understanding of replication and partitioning tradeoffs.

AI companion modes​

  • Explain simply
  • Diagnose my confusion
  • Revision mode
  • Connect forward / backward

Source-of-truth note​

This teaching unit is learner-facing guidance assembled from multiple canonical book routes. Use the listed source books as the primary conceptual spine for Reference and Selective Reading, and treat outside material as supporting enrichment only.
