Multi-Center druid via S3 deep storage replication


I need to use druid on 2 different EC2 data center I’ve already deployed druid on US. My idea is to use S3 deep storage to replicate the segment between 2 druid cluster.

Druid1 is writing segments on S3 US

Druid2 is writing segments on S3 EU

I synch via AWS Data pipeline that S3 segment from EU are copied to US then I need to reingest all the data from both center .

**I can’t use the raw data it’s too much data to transfert. **

Do you think it’s even possible ? if yes do you have any hint how to start ?
