Greetings R2DBC community!

We are delighted to announce the availability of R2DBC 1.0.0.M7, the seventh milestone release. The release is available from and ships with a few new modules: R2DBC Proxy and a Bill of Materials.

Introducing the Bill of Materials (bom) simplifies version management and consumption. Each project has its own theme how it names release trains. Want to hear a bit of trivia? We love Italy. We love the Dolomites and so name our release trains after Dolomiti towns. The first release train is named: Arabba. So let us introduce you to Arabba-M7.

We are also excited to announce that this is the first release shipping with R2DBC Proxy covering a multitude of use cases that are solved best with decoration: Tracing, Metrics, Observability.

The release train ships with the following modules:

  • R2DBC SPI (io.r2dbc:r2dbc-spi, io.r2dbc:r2dbc-spi-test)
  • R2DBC Client (io.r2dbc:r2dbc-client)
  • R2DBC PostgreSQL driver (io.r2dbc:r2dbc-postgresql)
  • R2DBC H2 driver (io.r2dbc:r2dbc-h2)
  • R2DBC Microsoft SQL Server driver (io.r2dbc:r2dbc-mssql)

New modules in this release:

  • R2DBC Proxy (io.r2dbc.r2dbc-proxy)
  • R2DBC BOM (io.r2dbc.r2dbc-bom)

Most notable SPI changes are:

  • Reinstated generated value (key) retrieval (Statement.returnGeneratedValues(…)) that moves key generation back to the driver.
  • Improved support for column metadata (ColumnMetadata).
  • Add support for ConnectionFactory discovery allowing connection creation without using driver-specific API.
  • R2DBC ships with specification documentation.
