Examples with Catalog io.trino.metadata.Catalog used on opensource projects

Example 1 with Catalog

use of io.trino.metadata.Catalog in project trino by trinodb.

the class ConnectorManager method createCatalog.

private synchronized void createCatalog(CatalogName catalogName, String connectorName, InternalConnectorFactory factory, Map<String, String> properties) {
    // create all connectors before adding, so a broken connector does not leave the system half updated
    CatalogClassLoaderSupplier duplicatePluginClassLoaderFactory = new CatalogClassLoaderSupplier(catalogName, factory.getDuplicatePluginClassLoaderFactory(), handleResolver);
    MaterializedConnector connector = new MaterializedConnector(catalogName, createConnector(catalogName, factory.getConnectorFactory(), duplicatePluginClassLoaderFactory, properties), duplicatePluginClassLoaderFactory::destroy);
    MaterializedConnector informationSchemaConnector = new MaterializedConnector(createInformationSchemaCatalogName(catalogName), new InformationSchemaConnector(catalogName.getCatalogName(), nodeManager, metadataManager, accessControlManager), () -> {
    });
    CatalogName systemId = createSystemTablesCatalogName(catalogName);
    SystemTablesProvider systemTablesProvider;
    if (nodeManager.getCurrentNode().isCoordinator()) {
        systemTablesProvider = new CoordinatorSystemTablesProvider(transactionManager, metadataManager, catalogName.getCatalogName(), new StaticSystemTablesProvider(connector.getSystemTables()));
    } else {
        systemTablesProvider = new StaticSystemTablesProvider(connector.getSystemTables());
    }
    MaterializedConnector systemConnector = new MaterializedConnector(systemId, new SystemConnector(nodeManager, systemTablesProvider, transactionId -> transactionManager.getConnectorTransaction(transactionId, catalogName)), () -> {
    });
    SecurityManagement securityManagement = connector.getAccessControl().isPresent() ? CONNECTOR : SYSTEM;
    Catalog catalog = new Catalog(catalogName.getCatalogName(), connector.getCatalogName(), connectorName, connector.getConnector(), securityManagement, informationSchemaConnector.getCatalogName(), informationSchemaConnector.getConnector(), systemConnector.getCatalogName(), systemConnector.getConnector());
    try {
        addConnectorInternal(connector);
        addConnectorInternal(informationSchemaConnector);
        addConnectorInternal(systemConnector);
        catalogManager.registerCatalog(catalog);
    } catch (Throwable e) {
        catalogManager.removeCatalog(catalog.getCatalogName());
        removeConnectorInternal(systemConnector.getCatalogName());
        removeConnectorInternal(informationSchemaConnector.getCatalogName());
        removeConnectorInternal(connector.getCatalogName());
        throw e;
    }
    connector.getEventListeners().forEach(eventListenerManager::addEventListener);
}

Example 2 with Catalog

the class CatalogSystemTable method cursor.

@Override
public RecordCursor cursor(ConnectorTransactionHandle transactionHandle, ConnectorSession connectorSession, TupleDomain<Integer> constraint) {
    Session session = ((FullConnectorSession) connectorSession).getSession();
    Builder table = InMemoryRecordSet.builder(CATALOG_TABLE);
    for (Map.Entry<String, Catalog> entry : getCatalogs(session, metadata, accessControl).entrySet()) {
        table.addRow(entry.getKey(), entry.getValue().getConnectorCatalogName().toString(), entry.getValue().getConnectorName());
    }
    return table.build().cursor();
}

Example 3 with Catalog

use of io.trino.metadata.Catalog in project trino by trinodb.

the class Server method updateConnectorIds.

private static void updateConnectorIds(Announcer announcer, CatalogManager metadata) {
    // get existing announcement
    ServiceAnnouncement announcement = getTrinoAnnouncement(announcer.getServiceAnnouncements());
    // automatically build connectorIds if not configured
    Set<String> connectorIds = metadata.getCatalogs().stream().map(Catalog::getConnectorCatalogName).map(Object::toString).collect(toImmutableSet());
    // build announcement with updated sources
    ServiceAnnouncementBuilder builder = serviceAnnouncement(announcement.getType());
    builder.addProperties(announcement.getProperties());
    builder.addProperty("connectorIds", Joiner.on(',').join(connectorIds));
    // update announcement
    announcer.removeServiceAnnouncement(announcement.getId());
    announcer.addServiceAnnouncement(builder.build());
