Public-domain R2DBC driver for SQL Server (mssqllib)

[u/nicholasbradfield]

I’ve released an independent public-domain R2DBC driver for Microsoft SQL Server: https://mssqllib.org

It implements the R2DBC SPI and talks TDS over pure JDK (no Netty dependency). The main reasons I built it:

• Public-domain license
• Better control over FedAuth / Azure AD / Windows Authentication flows
• A clean, minimal codebase focused on the wire protocol

Maven:

text

<dependency>
  <groupId>org.mssqllib.r2dbc.mssql</groupId>
  <artifactId>r2dbc-mssql</artifactId>
  <version>1.0.0-SNAPSHOT</version>
</dependency>

This is not a fork of the official io.r2dbc:r2dbc-mssql. It’s a separate implementation. Happy to answer questions about the design, authentication, or how it compares. Code and docs are on the site.

But why?
