org.apache.flink.table.api.TableException: Unsupported query: Merge Into

I am working on a Flink streaming job where I need to upsert data in the Hudi table. I am using merge into a query to upsert data in the Hudi table.

    Table table = tableEnv.fromDataStream(KafkaStreamTableDataStreamStream);
    tableEnv.createTemporaryView("table1", table);

    tableEnv.executeSql("Merge into target " +
            "USING table1 s0 " +
            "ON target.id = s0.id " +
            "WHEN MATCHED THEN UPDATE SET amount=s0.amount");

This query is working fine in spark-shell. But it is giving me Exception in thread "main" org.apache.flink.table.api.TableException: Unsupported query: Merge into .. in flink

Do merge into statement query work in the Flink job?

Solution

  • Flink doesn't support MERGE statements. This has been brought up for discussion but nothing has happened since then.
