"Simply reactive" with Vert.x, Mutiny, Hibernate Reactive and Quarkus
summary
Shows a working Vert.x HTTP server handling requests and a periodic task on a single event-loop thread, uses Testcontainers Postgres with Vert.x reactive SQL drivers, implements CRUD endpoints with Mutiny’s Uni/Multi (oneshot queries for SQL), and swaps raw SQL for Hibernate Reactive entities where Hibernate creates schema and issues select/insert. Then runs inside Quarkus dev mode that auto-starts the DB container, supports hot reload and continuous testing; performance paper finds similar overhead across reactive libs.
