[jira] [Created] (FLINK-24548) flink-connector-jdbc SQLException retry sleep have a problem

chenxy created FLINK-24548:
------------------------------

             Summary: flink-connector-jdbc  SQLException  retry sleep have a problem
                 Key: FLINK-24548
                 URL: https://issues.apache.org/jira/browse/FLINK-24548
             Project: Flink
          Issue Type: Improvement
          Components: API / DataStream
            Reporter: chenxy
         Attachments: 企业微信截图_20211014202406.png

版本：1.14 

类：/flink-connectors/flink-connector-jdbc/src/main/java/org/apache/flink/connector/jdbc/internal/JdbcOutputFormat.java

方法： public synchronized void flush() throws IOException {

行数：237行。 Thread.sleep(1000 * i);

问题： 该方法sleep时间是根据executionOptions.getMaxRetries()值进行循环，从0开始循环。

现象：1，第一次重试的时候出现异常时，直接导致sleep时间为0，导致直接抛出异常

           2，后面sleep 也会基于maxRetris的数值指数级变大。
