Module 5: Database Internals and Performance Engineering

Master database internals: 8KB pages, buffer pool LRU cache, B+ Trees vs LSM Trees vs Hash indexing, Bloom filters, cost-based query optimization, nested loop/hash/sort-merge joins, ACID transactions, MVCC tuple versioning, WAL crash recovery, table partitioning, and PostgreSQL performance tuning.

Core Engineering Competencies

  • Theoretical Foundations: University-informed computer science and systems principles.
  • Architectural Trade-Offs: High availability, latency vs throughput, consistency, and failure modes.
  • Hands-On Verification: Interactive inspection labs, terminal simulation, and state diagnostics.
  • Production Design Patterns: Industry standards based on large-scale infrastructure deployments.
