Debate: PostgreSQL on K8S
summary
Debate contrasts concrete costs and fixes: testing uses fio and pgbench benchmarks and a shared GitHub guide; Kubernetes runs the same PostgreSQL binaries from Debian images but adds added milliseconds to latency that payment systems find unacceptable; standard operators deliver automatic failover and self‑healing and are used in production, but cross‑region recovery needs extra work so a cross‑cluster replication workaround (cloudnative‑pg) is proposed — tradeoff is operational complexity and added networking/storage IO versus declarative deployments and portability.
