Getting Reactive with Relational Databases & R2DBC
summary
Explains that R2DBC is a non‑blocking reactive spec and shows a working MariaDB driver plus a Spring client: uses MariaDB R2DBC connector, Spring Data R2DBC and Project Reactor to get a connection from localhost (Docker), execute SQL against a todo table, insert a fifth row into four preloaded rows, and stream results. Demonstrates back‑pressure with a custom subscriber requesting two items at a time. Code runs successfully and maps rows into domain objects.
