It’s my pleasure to announce the first milestone of Spring Data R2DBC. Spring Data R2DBC is Spring's client project for R2DBC. With Spring Data R2DBC you get end to end reactive ad-hoc query execution and Spring Data repositories for relational databases.

Spring Data R2DBC embraces functional-reactive integration of relational databases by providing DatabaseClient as its central abstraction. The following example shows how to bootstrap DatabaseClient without spinning up a Spring context:

PostgresqlConnectionFactory connFactory = new PostgresqlConnectionFactory…

Imperative code eats threads at the pace of incoming requests while Software is eating the world. This post discusses the assumptions for reactive programming on the JVM and what this means for integrations – in particular, relational databases.

The motivation to come up with a post is the constant increase in reactive programming adoption while some major building blocks are not yet available – in particular, the question: What about relational databases?

What is Reactive Programming

There are a lot of answers about what Reactive Programming is and how this compares to Reactive Systems. I see Reactive Programming as a programming model that facilitates scalability and stability by creating event-driven non-blocking functional pipelines that react to availability and processability of resources. Deferred execution, concurrency and asynchronicity…
