Moving bulk data out of google cloud spanner database

Question

I have a requirement to move the data in bulk from cloud spanner instance what other option do I have apart from export?

Answer 1

Yes, you could probably use the Cloud Dataflow connector.

The Cloud Dataflow connector for Cloud Spanner lets you read data from and write data to Cloud Spanner in a Cloud Dataflow pipeline, optionally transforming or modifying the data. 

You can also create pipelines that transfer data between Cloud Spanner and other Google Cloud Platform products.

The Cloud Dataflow connector is the recommended method for efficiently moving data into and out of Cloud Spanner in bulk. 

For usage and other details refer to https://cloud.google.com/spanner/docs/dataflow-connector

Hope it works!!
