MariaDB Releases New R2DBC Connector MariaDB Corporation today announced the general availability of MariaDB Connector/R2DBC. The new MariaDB Connector for R2DBC exposes a non-blocking API that interacts with MariaDB databases, including MariaDB SkySQL, to create fully reactive solutions. Reactive Relational Database Connectivity (R2DBC) is a new, emerging standard in the Java world. R2DBC enables applications to benefit from reactive programming by using a stream-oriented approach to interact with relational databases. Unlike its JDBC predecessor, applications can use R2DBC to take advantage of declarative programming techniques to create more powerful, efficient and scalable Java Virtual Machine (JVM) solutions.
