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

Example 1 with MetadataManager

use of io.trino.metadata.MetadataManager 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);

    });
    CatalogName systemId = createSystemTablesCatalogName(catalogName);
    SystemTablesProvider systemTablesProvider;
    if (nodeManager.getCurrentNode().isCoordinator()) {
