Change Streams - Spanner to Spanner

[Nei11s]

Hello,

I'm just wondering if its possible to setup a pipeline to take the data from one spanner instance to a completely separate spanner instance?

I can see in the documentation its possible to send to BigQuery, but i'm unable to see anywhere if its possible to go from one spanner instance to another.

Thanks,

Hi @Nei11s,

Yes, you can set up a pipeline to transfer data from one Spanner instance to another. The Dataflow connector for Spanner is a good choice for this. It allows you to read from and write to Spanner in a Dataflow pipeline, while also giving you the option to transform or modify the data along the way. This document should help you understand better how to import, export, and modify data using Dataflow.

I hope the above information is helpful.
