Quarkus 0.19.1 released

We just released Quarkus 0.19.1.

This new version brings a lot of new extensions, especially in the persistence area.

Quarkus 0.19.1 is still targeting GraalVM 19.0.2 as we discovered a bug in GraalVM 19.1.0 that affects Quarkus.

The issue is already fixed but we are waiting for a 19.1.1 release.

What’s new?

Here are the main highlights of this release: MongoDB support, Neo4J support, Amazon DynamoDB support, Apache Tika support, Reactive Messaging MQTT support and better Hibernate ORM schema upgrade (useful for dev mode).

Hibernate ORM schema management improvements

We had a few issues with automatic schema upgrades handled by Hibernate ORM. Things are now smoother and we significantly improved the documentation to explain how to configure schema management in various situations.

New extensions

MongoDB extension

MongoDB needs no introduction as it’s probably the most widely used NoSQL datastore. We had a lot of users asking for MongoDB support in Quarkus and here we are: we now have a fully featured MongoDB client extension.

It supports imperative and reactive and comes with a lot of configuration properties to tune the client. And, of course, you can use it with GraalVM.

You can learn more about it in the MongoDB client guide.

Neo4j extension

Neo4j is a graph database management system focused not only on the data itself, but especially on the relations between data.

Neo4j offers Cypher, a declarative query language much like SQL. Cypher is used to query the graph, telling the database engine what patterns to match and how. Clients communicate over the so called Bolt protocol with the database.

Quarkus now offers a Neo4j extension so that you can easily use Neo4j with Quarkus in JVM and native mode.

Want to give it a try? We have a guide for you.

Amazon DynamoDB extension

Amazon DynamoDB is a key-value and document database available on AWS.

The first version of this extensions allow to leverage Amazon DynamoDB features in JVM and native mode but it is not fully "quarked" yet. Future iterations will bring Quarkus-style config and the ability to inject the client directly with CDI.

In the meantime, you can create your client manually and give us feedback about the configuration knobs you want us to expose.

Apache Tika extension

Apache Tika is a framework to extract data from documents (and especially binary ones such as PDF documents). With the Apache Tika Quarkus extension, just inject a TikaParser and you can extract the information from your documents. Yes, in native mode too.

Reactive Messaging MQTT connector

MQTT is a machine-to-machine/IoT connectivity protocol. Our reactive messaging layer is growing and we now have support for it.

Full changelog

We also fixed some issues and merged a lot of improvements all over the place.

Where is 0.19.0?

We found a regression in our Gradle support while releasing 0.19.0, that’s why we released 0.19.1 right away.
