----------------------------------
Summary: the result of aggregate SQL on streaming cannot write to upsert table sink
Key: FLINK-18626
URL:
https://issues.apache.org/jira/browse/FLINK-18626 Project: Flink
Issue Type: Improvement
Components: Connectors / JDBC, Table SQL / API
Affects Versions: 1.11.0
Reporter: gaoling ma
{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 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://***/laowufp_data_test',\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");
{code}
When I write the aggregate SQL results into upsert stream JDBC table sink, the program automatically exits with no hint.
The aggregate results suppose to be a restract stream, but another question is how to change the restract stream into upsert stream. Or there is a better way to continuous update the aggregate SQL results into JDBC table. Your comment is appreciated.
