This project contains the service provider interface for R2DBC implementations. This interface is intended to be terse to simplify implementation by database vendors and should not be used directly. It is expected that client libraries would be built upon this interface in order to expose a more humane interface for tools and developers to use.

This project is governed by the Spring Code of Conduct. By participating, you are expected to uphold this code of conduct. Please report unacceptable behavior to [email protected].

Artifacts can be found on Maven Central.

R2DBC uses GitHub as issue tracking system to record bugs and feature requests. If you want to raise an issue, please follow the recommendations below:

• Before you log a bug, please search the issue tracker to see if someone has already reported the problem.
• If the issue doesn't already exist, create a new issue.
• Please provide as much information as possible with the issue report, we like to know the version of R2DBC SPI that you are using and JVM version.
• If you need to paste code, or include a stack trace use Markdown ``` escapes before and after your text.
• If possible try to create a test-case or project that replicates the issue. Attach a link to your code or a compressed file containing your code.

You don't need to build from source to use R2DBC SPI (binaries in Maven Central), but if you want to try out the latest and greatest, R2DBC SPI can be easily built with the maven wrapper. You also need JDK 1.8 and Docker to run integration tests.

 $ ./mvnw clean install

If you want to build with the regular mvn command, you will need Maven v3.5.0 or above.

Also see CONTRIBUTING.adoc if you wish to submit pull requests, and in particular please sign the Contributor's Agreement before your first change, however trivial.
