Red Hat SummitMaking open source more inclusive
Red Hat is committed to replacing problematic language in our code, documentation, and web properties. We are beginning with these four terms: master, slave, blacklist, and whitelist. Because of the enormity of this endeavor, these changes will be implemented gradually over several upcoming releases. For more details, see our CTO Chris Wright’s message.
Configure a data source for your Quarkus application using extensions for built-in database drivers and connect your application to a relational database. When you want to add persistent data storage to your application, you must connect your application to a relational database. To achieve this, you use a data source that you connect to your application using a database driver. You can connect your Quarkus application to one or multiple data sources.
You can use the data source management functionalities integrated into Quarkus to:
- configure your application to use one or multiple data sources
- obtain references to data sources in your code
- view and set pool tuning configuration properties
In Quarkus applications, you can use two types of database drivers to connect your application to a relational database. You can use multiple data sources of both types in one application simultaneously:
- JDBC drivers
- that use the standard JDBC API that provides database connectivity for Java-based application. Quarkus JDBC drivers manage database connections using Agroal, a fast, light-weight, and highly scalable database connection pool implementation that is integrated with other features of Quarkus, including security, transaction management and health checks.
- Reactive drivers
- that are based on the data source driver implementation in Eclipse Vert.x. Eclipse Vert.x reactive data source drivers provide the non-blocking and reactive network-related features of Quarkus and are suitable for applications that are designed to be highly scalable and event-driven.
You can configure both types of data source drivers using a set of unified and flexible configuration options that Quarkus provides.
