4.2. Technology Preview artifacts introduced in this release
The following artifacts are provided as Technology Preview in this release.
The Eclipse Vert.x reactive MSSQL client is a client for Microsoft SQL server. It is an API that helps in database scalability and has low overhead. Since the API is reactive and non-blocking you can handle multiple database connections with a single thread.
The Eclipse Vert.x HTTP proxy is a reverse proxy. Using this module you can easily create proxies. The proxy server can also dynamically resolve the DNS queries from origin server.
The Eclipse Vert.x web proxy enables you to mount an Eclipse Vert.x HTTP proxy in an Eclipse Vert.x web router.
Open Telemetry tracing is supported. You can use Open Telemetry for HTTP and event bus tracing.
This Eclipse Vert.x web session store enables you to save session data in an Infinispan cache. The module is implemented on the Infinispan client so you can use it with either stand alone or clustered Eclipse Vert.x applications.
The Eclipse Vert.x authentication module
io.vertx.ext.auth.AuthProviderinterface has been split into two new interfaces:
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
Userobject. This meant that the provider was responsible for both authentication and authorization of the user.
In Eclipse Vert.x 4, the
Userobject instances are not associated with a particular authentication provider. So you can authenticate and authorize a user using different providers.
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 clientNote
