>          Components: API / DataStream

> 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。
