Sufficient for immediately’s concept; let’s see this integration in follow. It is going to be a easy software utilizing Java, Maven, and Java SE. 

Step one is to have an put in PostgreSQL. To make it simpler, let’s use docker and run the next command:

docker run --rm=true --name postgres-instance -e POSTGRES_USER=micronaut 
           -e POSTGRES_PASSWORD=micronaut -e POSTGRES_DB=airplane 
           -p 5432:5432 postgres:14.1

Ultrafast With PostgreSQL and MicroStream

On this instance, let’s use an airplane pattern the place we’ll have a number of planes and fashions that we’ll filter by producer. Step one of our challenge is in regards to the Maven dependencies. In addition to the CDI, we have to embrace the MicroStream integration following the MicroStream relational integration, and moreover, the PostgreSQL driver.


The second step is to overwrite the configuration for utilizing a relational database. First, create DataSource, after which we’ll inject it after which apply it to the StorageManager.

    non-public static ultimate String JDBC = "microstream.postgresql.jdbc";
    non-public static ultimate String USER = "microstream.postgresql.person";
    non-public static ultimate String PASSWORD = "microstream.postgresql.password";

    public DataSource get() 
        Config config = ConfigProvider.getConfig();
        PGSimpleDataSource dataSource = new PGSimpleDataSource();
        dataSource.setUrl(config.getValue(JDBC, String.class));
        dataSource.setUser(config.getValue(USER, String.class));
        dataSource.setPassword(config.getValue(PASSWORD, String.class));
        return dataSource;

class SQLSupplier implements Provider<StorageManager> 

    non-public DataSource dataSource;

    public StorageManager get() 
        SqlFileSystem fileSystem = SqlFileSystem.New(
        return EmbeddedStorage.begin(fileSystem.ensureDirectoryPath("microstream_storage"));

    public void shut(@Disposes StorageManager supervisor) 

With the configuration prepared, the subsequent step is to create the entity and its repository. In our pattern, we’ll make Airplane and Airport as entity and repository, respectively.

public interface Airport extends CrudRepository<Airplane, String> 
    Checklist<Airplane> findByModel(String mannequin);

public class Airplane 
    non-public String id;
    non-public String mannequin;
    non-public Yr yr;

    non-public String producer;

public static void fundamental(String[] args) 

strive (SeContainer container = SeContainerInitializer.newInstance().initialize()) 
    Airplane airplane = Airplane.id("1").mannequin("777").yr(1994).producer("Boing");
    Airplane airplane2 = Airplane.id("2").mannequin("767").yr(1982).producer("Boing");
    Airplane airplane3 = Airplane.id("3").mannequin("747-8").yr(2010).producer("Boing");
    Airplane airplane4 = Airplane.id("4").mannequin("E-175").yr(2023).producer("Embraer");
    Airplane airplane5 = Airplane.id("5").mannequin("A319").yr(1995).producer("Airbus");
    Airport airport = container.choose(Airport.class).get();
    airport.saveAll(Checklist.of(airplane, airplane2, airplane3, airplane4, airplane5));
    var boings = airport.findByModel(airplane.getModel());
    var all = airport.findAll().toList();
    System.out.println("The boings: " + boings);
    System.out.println("The boing fashions avialables: " + boings.measurement());
    System.out.println("The airport whole: " + all.measurement());
