WildFly Swarm Architecture

From Wildfly to WildFly Swarm

• Architecture Comparison

• Pro Vs Con

WildFly Architecture

WildFly Swarm Architecture

Uberjar Architecture

Extended JBoss Modules

public class BootModuleLoader extends ModuleLoader {
    public BootModuleLoader() throws IOException {
        super(new ModuleFinder[]{
                new BootstrapClasspathModuleFinder(),
                new BootstrapModuleFinder(),
                new ClasspathModuleFinder(),
                new ContainerModuleFinder(),
                new ApplicationModuleFinder(),
                new FlattishApplicationModuleFinder(),
        });
    }

Pro Vs Con

• Good at Move Application from WildFLy

• JBoss Modules - class loading too complex

How to Develop Swarm Teiid

• Develop Feature Pack

• Develop Config API

• Develop CDI Bean

WildFly Swarm Architecture

Develop Feature Pack

• feature pack - a lightweight artifact that contains a complete description of a set of server features

• Maven plugin build dist from feature pack

Develop Config API

• Depend on Runtime Server

• Generated by Maven plugin

Develop CDI Bean

@WildFlyExtension(module = "org.jboss.teiid", classname = "org.teiid.jboss.TeiidExtension")
@MarshalDMR
public class TeiidFraction extends Teiid implements Fraction 

Develop CDI Bean

@Inject
@Named(DefaultSocketBindingGroupProducer.STANDARD_SOCKETS)
private SocketBindingGroup group;

this.group.socketBinding(new SocketBinding("teiid-jdbc").port(this.jdbcPort));
this.group.socketBinding(new SocketBinding("teiid-odbc").port(this.odbcPort));

Develop CDI Bean

@Inject
@Any
private Instance infinispan;

infinispan.cacheContainer("teiid-cache",
                cc -> cc.defaultCache("resultset")
                        .localCache("resultset-repl",
                                c -> c.lockingComponent(l -> l.isolation(LockingComponent.Isolation.READ_COMMITTED))
                                      .transactionComponent(t -> t.mode(TransactionComponent.Mode.NON_XA))
                                      .evictionComponent(e -> e.strategy(EvictionComponent.Strategy.LIRS).maxEntries(1024L))
                                      .expirationComponent(e -> e.maxIdle(7200000L)))
                        .localCache("resultset",
