将BigQuery数据传输服务（DCM）数据移至另一个项目

Question

我在GCP项目A的数据集A中有用于Campaign Manager设置的BigQuery数据传输服务。我想将其移至项目B中的数据集B。如何移动现有数据并设置有损失的BigQuery Transfer数据和重复项？

Answer 1

I'm afraid you would have to:

1. Copy the relevant tables from dataset A to dataset B
2. Set up the transfer service again for dataset B (assuming it can be done if the tables already exist in the target dataset)
3. De-dup the data yourself.

A workaround, that achieve something similar but not exactly what you asked, is to create views of relevant tables in dataset A into dataset B.

By doing so, these views will behave like proper tables in dataset B and you don't have to worry about de-deplication, data loss, and setting up again the data transfer. The downside is that you will have to keep dataset A around.

以下是迁移服务的迁移方式：

1. 在项目B中启用了转移服务。
2. 一旦数据开始到达数据集B，历史 从复制数据（从开始到MIN（partition_date）-1） 数据集A到数据集B中的适当分区。
3. 验证了项目A后，已停止了项目A中的传输服务 分区计数和行计数。
