An epic tale: comparing JDBC and R2DBC in a real-world scenario (Part 1/2)

The whole quest revolves around a simple but hard-to-answer question: “does it makes any sense to use R2DBC?”

Googling around it’s possible to find several benchmarks which precisely state that R2DBC is awesome with high concurrency. Those benchmarks however are built on a scenario that is far far away from a real database-intensive application. They usually test a simple “get” on a database table: that is way too simplistic.
