Global Payments: Subsecond Performance Worldwide
summary
Global Payments migrates a merchant transaction workload from SQL Server to CockroachDB, consolidating 47 database flavors toward eight and replacing expensive AG clusters with a cloud‑native, multi‑region replication factor of five design that uses Kubernetes on GCP and a global load balancer. Tests hit ~1,000 TPS on ~120 Cockroach cores versus 250 TPS on a 128‑core SQL Server box, survive Gremlin chaos (node loss, network faults) with nominal latency impact, and use 221 quorum placement, Prometheus/Grafana monitoring, and planned EU data sovereignty.
