> jdbc connector 定时调度 flush 存在内存泄漏 bug
> ------------------------------------
>
> Key: FLINK-28205
> URL: https://issues.apache.org/jira/browse/FLINK-28205
> Project: Flink
> Issue Type: Bug
> Components: Connectors / JDBC
> Affects Versions: 1.15.0, 1.13.6, 1.14.5
> Reporter: michaelxiang
> Priority: Major
>
> 类路径：org.apache.flink.connector.jdbc.internal.JdbcBatchingOutputFormat
> bug位置：open方法，调度线程Runnable 实例
> 采用flink-connector-jdbc 进行写入时， 定时调度线程进行 flush 出现异常情况时对 RuntimeException
> 进行了捕获，这会导致在新数据到达 Task 前不会发生故障退出，因而定时调度线程则会不停的通过创建RuntimeException 进行包裹 上一个创建的
> flushException，对于flushException 无法释放引用被GC回收，从而导致内存泄漏。
