upsert table sink )

> Key: FLINK-18626
> URL: https://issues.apache.org/jira/browse/FLINK-18626
> Project: Flink
> Issue Type: Bug
> Components: Connectors / JDBC, Table SQL / API
> Affects Versions: 1.11.0
> Reporter: gaoling ma
> Priority: Major
>
> {code:java}
> StreamExecutionEnvironment bsEnv =
> StreamExecutionEnvironment.getExecutionEnvironment();
> EnvironmentSettings bsSettings =
> EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build();
> StreamTableEnvironment bsTableEnv = StreamTableEnvironment.create(bsEnv,
> bsSettings);
> bsEnv.setParallelism(1);
> bsTableEnv.executeSql("CREATE TABLE bbb (\n" +
> ......
> ") WITH (\n" +
> " 'connector' = 'jdbc',\n" +
> " 'url' = 'jdbc:mysql://***/***',\n" +
> " 'table-name' = 'bbb',\n" +
> " 'driver' = 'com.mysql.cj.jdbc.Driver',\n" +
> " 'username' = '***',\n" +
> " 'password' = '***'" +
> ")");
> bsTableEnv.executeSql("CREATE TABLE aaa(\n" +
> " `area_code` VARCHAR,\n" +
> " `stat_date` DATE,\n" +
> " `index` BIGINT,\n" +
> " PRIMARY KEY (area_code, stat_date) NOT ENFORCED" +
> ") WITH (\n" +
> " 'connector' = 'jdbc',\n" +
> " 'url' = 'jdbc:mysql://***/***',\n" +
> " 'table-name' = 'aaa',\n" +
> " 'driver' = 'com.mysql.cj.jdbc.Driver',\n" +
> " 'username' = '***',\n" +
> " 'password' = '***'\n" +
> ")");
>
> bsTableEnv.executeSql("INSERT INTO aaa SELECT area_code,
> CURRENT_DATE AS stat_date, count(*) AS index FROM bbb WHERE is_record = '是'
> GROUP BY area_code");
> // Table table = bsTableEnv.sqlQuery("SELECT area_code,
> CURRENT_DATE AS stat_date, count(*) AS index FROM bbb WHERE is_record = '是'
> GROUP BY area_code");
> // DataStream<Tuple2<Boolean, Row>> retractStream =
> // bsTableEnv.toRetractStream(table, Row.class);
> // retractStream.print();
> // bsEnv.execute();
> {code}
> When I write the aggregate SQL results of bounded streaming into upsert
> stream JDBC table sink, the program automatically exits with no hint. The
> result table is also empty which it should not be.
> When I use commented code above, which convert the aggregate SQL results into
> retractStream, and the print result is normally.
> When I use unbounded streaming source like kafka and comment the code as
> above, the program runs normally.
