             Summary: Support limit push down in DATAGEN connector.
                 Key: FLINK-25379
                 URL: https://issues.apache.org/jira/browse/FLINK-25379
             Project: Flink
          Issue Type: Improvement
          Components: Table SQL / API
            Reporter: Moses


I used datagen to generate data, and I found that the source is never ending.
{code:sql}
SET sql-client.execution.result-mode=TABLEAU;
CREATE TABLE datagen (a STRING) WITH ('connector'='datagen');
SELECT * FROM datagen LIMIT 10;
{code}

I think it's advisable for us to push limit down in datagen source.
