Enable HTTP compression for REST client only

[geoand]

Discussed in #46414

^{Originally posted by jdussouillez February 21, 2025}
I have a REST API that acts like a middleware between clients and another "external" REST API.

To send requests to the external API, I use a REST client. I want to enable HTTP compression in the REST client, but not in my REST API. Mostly because I have a nginx in front of my REST API that handles compression so it's handled outside of the Quarkus app.

Is this possible?

From what I saw in the documentation, to enable HTTP compression in REST client, I have to use quarkus.http.enable-compression=true.

https://quarkus.io/guides/rest-client#receiving-compressed-messages

REST Client also supports receiving compressed messages using GZIP. You can enable the HTTP compression support by adding the property quarkus.http.enable-compression=true.

But this option will also enable global HTTP compression for my API: https://quarkus.io/guides/http-reference#http-compression

I might find some way to make what I want, but I'm wondering if there is a way to easily enable compression only for REST client.

@jdussouillez can you try #46417 please?

[jdussouillez]

I tried but unfortunately I need more time to figure out how to use your branch into my project.

I cloned your repo, switched your branch, run MAVEN_OPTS="-Xmx4g" ./mvnw install -Dquickly and followed https://github.com/quarkusio/quarkus/blob/main/CONTRIBUTING.md#updating-the-version by changing the group id and version, but I have some trouble with quarkus-rest-jackson dependency:

'dependencies.dependency.version' for io.quarkus:quarkus-rest-jackson:jar is missing

When explicitly adding <version>999-SNAPSHOT</version> on the dependency, I have a lot of cannot find symbol: class Inject build errors.

I'll find a solution and try ASAP

FWIW, when I build Quarkus locally I use:

mvn -T 1C -DskipDocs -DskipTests -DskipITs -Dinvoker.skip -DskipExtensionValidation -Dskip.gradle.tests -Dskip.gradle.build -Dtruststore.skip clean install -Prelocations

Then I use:

      <dependency>
        <groupId>io.quarkus</groupId>
        <artifactId>quarkus-bom</artifactId>
        <version>999-SNAPSHOT</version>
        <type>pom</type>
        <scope>import</scope>
      </dependency>

as the BOM in any test application

It's not my day I think.

What is the output of mvn -version?

I have:

Same. I'm using SDKMan and switched to 17 (my apps are 21) to build Quarkus

I am out of ideas unfortunately

[geoand]

New week, perhaps any luck on a new attempt to build this?

[jdussouillez]

Same as last week unfortunately. I checked and Quarkus 999-SNAPSHOT (built from your branch) is well installed in my .m2 (file modification date matches), but I have the same issues as last week.

I'm thinking about adding a temporary module in the Quarkus project. This module will contain a endpoint calling a REST client to test the new options you added. So I don't use "external" dependencies installed on my machine but the project modules themselves.
