Below is the sample code using Flink 1.10
public class Test {
public static void main(String... args) throws Exception {
EnvironmentSettings bsSettings =
EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
final StreamExecutionEnvironment env =
StreamExecutionEnvironment.getExecutionEnvironment();
env.setStateBackend((StateBackend) new
RocksDBStateBackend("file:///tmp"));
StreamTableEnvironment bsTableEnv =
StreamTableEnvironment.create(env, bsSettings);
Properties properties = new Properties();
properties.setProperty("bootstrap.servers", "localhost:9092");
properties.setProperty("group.id", "test");
FlinkKafkaConsumer<String> consumer1 = new FlinkKafkaConsumer<>(
java.util.regex.Pattern.compile("test-topic1"),
new SimpleStringSchema(),
properties);
FlinkKafkaConsumer<String> consumer2 = new FlinkKafkaConsumer<>(
java.util.regex.Pattern.compile("test-topic2"),
new SimpleStringSchema(),
properties);
DataStream<String> stream1 = env.addSource(consumer1);
DataStream<String> stream2 = env.addSource(consumer2);
bsTableEnv.createTemporaryView("sample1", stream1);
bsTableEnv.createTemporaryView("sample2", stream2);
Table result = bsTableEnv.sqlQuery("SELECT * FROM sample1
INNER JOIN sample2 on sample1.f0=sample2.f0");
result.printSchema();
bsTableEnv.toRetractStream(result, Row.class).print();
bsTableEnv.execute("sample job");
}
}
