Example 1 with TableSourceFactoryContextImpl

use of org.apache.flink.table.factories.TableSourceFactoryContextImpl in project flink by apache.

the class HiveTableFactoryTest method testGenericTable.

@Test
public void testGenericTable() throws Exception {
    final TableSchema schema = TableSchema.builder().field("name", DataTypes.STRING()).field("age", DataTypes.INT()).build();
    catalog.createDatabase("mydb", new CatalogDatabaseImpl(new HashMap<>(), ""), true);
    final Map<String, String> options = Collections.singletonMap(FactoryUtil.CONNECTOR.key(), "COLLECTION");
    final CatalogTable table = new CatalogTableImpl(schema, options, "csv table");
    catalog.createTable(new ObjectPath("mydb", "mytable"), table, true);
    final Optional<TableFactory> tableFactoryOpt = catalog.getTableFactory();
    assertTrue(tableFactoryOpt.isPresent());
    final HiveTableFactory tableFactory = (HiveTableFactory) tableFactoryOpt.get();
    final TableSource tableSource = tableFactory.createTableSource(new TableSourceFactoryContextImpl(ObjectIdentifier.of("mycatalog", "mydb", "mytable"), table, new Configuration(), false));
    assertTrue(tableSource instanceof StreamTableSource);
    final TableSink tableSink = tableFactory.createTableSink(new TableSinkFactoryContextImpl(ObjectIdentifier.of("mycatalog", "mydb", "mytable"), table, new Configuration(), true, false));
    assertTrue(tableSink instanceof StreamTableSink);
}

Example 2 with TableSourceFactoryContextImpl

use of org.apache.flink.table.factories.TableSourceFactoryContextImpl in project flink by apache.

the class CatalogSchemaTable method findAndCreateTableSource.

private Optional<TableSource<?>> findAndCreateTableSource() {
