The Complete Handbook of High-Performance Database Tuning
In-depth breakdown of query planning, index cardinality, connection pooling, and replication lag optimization.
Table of Contents
1. Understanding the Query Execution Engine
Deep-dive into index scans vs bitmap heap scans, analyzing cost formulas, and tuning buffer cache hit ratios.
2. Advanced B-Tree and BRIN Indexing Topologies
Optimize multi-terabyte timeseries tables using Block Range Indexes and composite partial indexes.
3. Connection Pooling and PgBouncer Tuning
Mitigate transaction thrashing and CPU context switches by scaling connection pool concurrency to match CPU core counts.
4. Multi-Region Read Replicas and Write Consistency
Balance eventual consistency against linearizable reads using synchronous commit levels and raft-backed consensus.
