我们将数据流式传输到BigQuery（使用动态目标）的数据流管道在作业日志中显示了许多异常。所有这些都是javax.net. ssl.SSLException：连接重置异常。我在下面提供了堆栈跟踪，但想知道这是否会导致数据丢失？

这些错误很多（每天数百个），似乎与以下工作日志一致：

Execution of work for computation 'P6' on key '-REDACTED-' failed with uncaught 
exception. Work will be retried locally.

我是否可以得出结论，工作在工作人员本地进行了有效重试，并且没有数据丢失，但作业日志中仍然提到了异常？

我发现仅仅通过查看不同的日志来理解哪些错误实际上导致了数据丢失是非常令人困惑的。

示例堆栈跟踪：
