             Summary: JDBCUpsertOutputFormat  no need to create schedule flush when  flushMaxSize = 1
                 Key: FLINK-15389
                 URL: https://issues.apache.org/jira/browse/FLINK-15389

          Issue Type: Improvement
          Components: Connectors / JDBC
    Affects Versions: 1.9.1
            Reporter: xiaodao


when flushMaxSize set 1; then it will call fush  func every time;  it's no need to create schedule to flush data.

if (flushIntervalMills != 0)  it's better to modify with

if (flushIntervalMills != 0 and flushMaxSize != 1)
