Summary
Nine runnable Spring Boot modules demonstrate Open J Proxy (OJP), a Type 3 JDBC driver and Layer 7 database proxy that centralizes HikariCP connection pools on a remote server via gRPC.
Topics progress from basic CRUD to circuit breaking, slow-query segregation, load testing, multi-node failover, and production hardening with SSL and Docker/K8s. Requires Java 21, Docker, and Maven 3.9+; pins OJP 0.4.7-beta and Spring Boot 3.3.x.
