将BigQuery表从一个项目导出到另一个项目 [英] Exporting BigQuery table from one project to another
问题描述
我正在尝试将存储在Google Cloud Project(Project1)中的BigQuery表(Table1)复制到另一个Google Cloud Project(Project2).该表按TB的顺序排列.这样做的最佳方法是什么，这样我就不必在本地导出表了?我应该将表格从Project1导出到Google Cloud Storage，然后再导出到Project2吗?还是有更好的方法?
I'm trying to copy a BigQuery table (Table1) stored within a Google Cloud Project (Project1) to another Google Cloud Project (Project2). The table is on the order of TBs. What's the best way to do this so that I don't have to export the table locally? Should I export the table from Project1 to Google Cloud Storage, and then to Project2? Or is there a better way?
