将数据流式传输到Google BigQuery表中：SocketTimeoutException，502错误的网关，500个内部服务器错误警告

Question

我们正在使用Camel BigQuery API（版本2.20）将记录从ActiveMQ服务器（版本5.14.3）上的消息队列流式传输到Google BigQuery表中。

我们已经在Spring框架中实现并部署了流传输机制作为XML路由定义，因此：

上面的方法似乎有效，而且我们似乎正在以高速率发送消息/记录（一条路由每分钟处理超过12,000条消息），但是我们的日志显示了很多SocketTimeoutException，502错误网关和500内部服务器错误警告：

2019-10-21 15:33:13 | WARN  | DefaultErrorHandler | Failed delivery for (MessageId: XXX on ExchangeId: XXX). On delivery attempt: 0 caught: java.net.SocketTimeoutException: connect timed out

2019-10-24 12:46:53 | WARN  | DefaultErrorHandler | Failed delivery for (MessageId: XXX on ExchangeId: XXX). On delivery attempt: 0 caught: com.google.api.client.googleapis.json.GoogleJsonResponseException: 502 Bad Gateway

2019-10-25 12:33:33 | WARN  | DefaultErrorHandler | Failed delivery for (MessageId: XXX on ExchangeId: XXX). On delivery attempt: 0 caught: com.google.api.client.googleapis.json.GoogleJsonResponseException: 500 Internal Server Error

问题

1. 我对onException对象的使用通常/在语法上正确吗（除非对[[redeliveryPolicy属性进行微调）？还是我错过了其他任何东西？

2. 我感兴趣的第一条警告消息说，“

   交付时尝试：0

被捕获：java.net.SocketTimeoutException”。我的日志文件中没有[[not具有“尝试传递时：1”，“尝试传递时：2”等）。这是否意味着给定消息的后续传递尝试成功？就将数据流传输到GCP而言，我应该将“ SocketTimeoutException”，“ 500 Internal Server Error”和“ 502 Bad Gateway”彼此区别对待，还是使用相同的onException + redeliveryPolicy OK？] >

3. 还有其他方法可以改善这种将数据流式传输到GCP的Camel / Google API方法的性能吗？ Camel / Google API可以支持消息批处理以减少GCP插入操作的数量吗？我已经在使用具有重复数据删除功能的双流（CamelGoogleBigQueryInsertId）。
