Synchronous vs Asynchronous Replication

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/concepts/cluster-03-replication-mechanics/08-synchronous-versus-asynchronous-replication-primary.md
  • App: architecture
  • Semester: semester-06-databases-distributed
  • Module: module-03-replication-partitioning
  • Unit kind: concept
  • Curation level: module_curated

Learning objectives​

  • Explain Synchronous vs Asynchronous Replication in terms of topology, failure handling, and scaling tradeoffs instead of feature lists.
  • Use Synchronous vs Asynchronous Replication to predict what breaks or changes when data is copied, partitioned, or rebalanced across nodes.
  • Use database-internals, database-system-concepts, ddia 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

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
  • Socratic tutor
  • Challenge my understanding
  • Diagnose my confusion
  • 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 Synchronous vs Asynchronous Replication, and treat outside material as supporting enrichment only.
