我在servlet中打包了一个数据流作业(在BlockingDataflowPipelineRunner模式下运行,每天由CRON作业(在AppEngine中)触发)。它在使用Jetty在本地启动时工作,但在使用AppEngine部署时不起作用。 编辑:这是我得到的错误。在日志记录中,这是在Dataflow日志之后可以找到的内容(虽然我看不到任何“停止数据流工作人员 ...

我们有一个非常简单的管道,从GCS读取数据,执行一个简单的ParDo,然后将结果写入BigQuery。它可以自动扩展到50个虚拟机,在GCP上运行,并且不做任何花哨的事情。 从GCS读取所有数据(约10B记录 但是,当它到达BigQuery写入(使用BigQueryIO)时,它会立即减慢速度——尽管它只需要写入大约1M条记录(约60MB)。仅这一步就需要...
