Replication lag often appears when PostgreSQL workloads move from single-region to distributed setups. What looks stable locally can behave very differently once network latency and cross-region coordination are involved.

Our whitepaper benchmarks replication lag in single-region vs multi-region PostgreSQL architectures using pgbench and HammerDB, with insights and recommendations for running distributed clusters.
