Bootiful Spring Boot
summary
Spring Boot 3.x with Java 21+ powers a demo “Pooch Palace” service that wires Spring Data JDBC, PGVector, OpenAI via Spring AI, and a modular event pipeline that guarantees delivery by republishing outstanding events from a DB table; the RAG pipeline finds Prancer from vectorized dog records and returns a typed suggestion. Benchmarks show virtual threads halving end-to-end latency (≈11s vs 22s, 3.3 vs 1.8 req/s), a 1.5s 1B-row processing example, and a GraalVM native image build yielding ~170 MB RSS. The demo uses Spring modulith and PGVector/OpenAI RAG and works end-to-end.
