4.2. Technology Preview artifacts introduced in this release

The following artifacts are provided as Technology Preview in this release.

  • vertx-auth-webauthn

    The Eclipse Vert.x authentication module io.vertx.ext.auth.AuthProvider interface has been split into two new interfaces:

    • io.vertx.ext.auth.authentication.AuthenticationProvider
    • io.vertx.ext.auth.authorization.AuthorizationProvider

Authentication is a new feature in Eclipse Vert.x 4. In earlier releases, you could only check if a user was authorized to perform the tasks on the User object. This meant that the provider was responsible for both authentication and authorization of the user.

In Eclipse Vert.x 4, the User object instances are not associated with a particular authentication provider. So you can authenticate and authorize a user using different providers.

  • vertx-opentracing

    Eclipse Vert.x 4 supports distributed tracing. You can use tracing to monitor microservices and identify performance issues.

    Eclipse Vert.x 4 integrates with OpenTracing system.

    The following Eclipse Vert.x components can log traces:

    • HTTP server and HTTP client
    • Eclipse Vert.x SQL client

    • Eclipse Vert.x Kafka client
