--------------------------
Resolution: Won't Do
> 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
> Priority: Major
> Labels: features
> 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。
