Logs distribution between storages based on tenant

I have Loki installation that use AWS s3 as logs storage configured as described in the manuals like this:

        shared_store: s3
        active_index_directory: /var/loki/index
        cache_location: /var/loki/cache
        cache_ttl: 336h
        s3: s3://eu-central-1/
        bucketnames: mybucket-0,mybucket-1,mybucket-2,mybucket-3
        access_key_id: ${AWS_ACCESS_KEY_ID}
        secret_access_key: ${AWS_SECRET_ACCESS_KEY}
        s3forcepathstyle: true

Now I need to add one more tenant and I have a requirement to store these logs on s3 but in another region in US and then use it ONLY for logs from this tenant.
Is it possible to implement?

I’d be using 2 seperate loki instances in that case. That’s what I’m doing. I have 2 containers and expose a different port for each container. You might need another multi-tenant-proxy container but that’s very little overhead. I dont know what app you use to scrape the logs in the first place. I had a little trouble getting the clients: section working in promtail so I switched to fluentd as the sender and , after a bit more fiddling, got that to work.
