Reactive Relational Database Connectivity (R2DBC) is a specification for SQL database access on the JVM. Non-blocking. Backpressure-aware. Community-driven. Open Source.

Based on the Reactive Streams specification 💫. R2DBC is founded on the Reactive Streams specification, which provides a fully-reactive non-blocking API.

Works with relational databases 🔋. In contrast to the blocking nature of JDBC, R2DBC allows you to work with SQL databases using a reactive API.

Supports scalable solutions ↔️. With Reactive Streams, R2DBC enables you to move from the classic "one thread per connection" model to a more powerful and scalable approach.

Provides an open specification 👐. R2DBC is an open specification and establishes a Service Provider Interface (SPI) for driver vendors to implement and clients to consume.

This organization hosts repositories for the specification, drivers, and support components (Connection Pooling, R2DBC Proxy).
