# perftests-quarkus

This is a test for Quarkus to handle large projets, in quantity of objects to manage.

To use this project, you have to generate the _actual_ code:

1. Set the root path in `src/main/java/fr/spacefox/perftests/quarkus/generator/Generator.java` constant `ROOT_PATH` to
   the _actual_ path of your project sources.
2. You may change the number of elements to generate with `ELEMENTS` in the same file.
3. Run the Generator: now you have a giant Quarkus project ready to be used!
4. Build and play! You can keep the tests, they will run in a _reasonable_ amount of time.
5. You can run some kind of performance tests by using `perfs.jmx` in Apache JMeter

See also [the Spring Boot version](https://git.spacefox.fr/spacefox/perftests-springboot).

Requirements:

- JRE ⩾ 21
- PostgreSQL (you may use `src/test/docker/compose.yaml`)

**Note: generating too much `ELEMENTS` will not work due to Quarkus internals**.
Actual limit with this project is somewhere between 4100 and 4200.

Generated arborescence kind of follow the hexagonal / ports & adapters architecture, so Panache ORM is used with its
repository variant:

```
fr.spacefox.perftests.quarkus
    .core
        .port
            .data
                EntityNDatasourcePort.java
        .serviceN
            .model
                ModelN.java
            ServiceN
    .data
        .entityN
            EntityN.java
            EntityNRepository.java
            Mapper.java
    .rest
        .endpointN
            .schema
                SchemaN.java
            EndpointNResource.java
            Mapper.java
+ tests
```

--------------------------

## Running the application in dev mode

You can run your application in dev mode that enables live coding using:

```shell script
./mvnw quarkus:dev
```

> **_NOTE:_**  Quarkus now ships with a Dev UI, which is available in dev mode only at <http://localhost:8080/q/dev/>.

## Packaging and running the application

The application can be packaged using:

```shell script
./mvnw package
```

It produces the `quarkus-run.jar` file in the `target/quarkus-app/` directory.
Be aware that it’s not an _über-jar_ as the dependencies are copied into the `target/quarkus-app/lib/` directory.

The application is now runnable using `java -jar target/quarkus-app/quarkus-run.jar`.

If you want to build an _über-jar_, execute the following command:

```shell script
./mvnw package -Dquarkus.package.jar.type=uber-jar
```

The application, packaged as an _über-jar_, is now runnable using `java -jar target/*-runner.jar`.

## Creating a native executable

You can create a native executable using:

```shell script
./mvnw package -Dnative
```

Or, if you don't have GraalVM installed, you can run the native executable build in a container using:

```shell script
./mvnw package -Dnative -Dquarkus.native.container-build=true
```

You can then execute your native executable with: `./target/perftests-quarkus-1.0.0-SNAPSHOT-runner`

If you want to learn more about building native executables, please consult <https://quarkus.io/guides/maven-tooling>.
