Hi Patrik, Thanks for your reply! I think I'll go with implementing the dynamic solution for my project: we're fine with causal eventual consistency, and we think being available during intra-DC netsplits will be beneficial. Another reason I didn't mention is that we need a particular schema

Hi Igor, There are several reasons, such as: - we believe that it's useful to have the strong consistency with single-writer within one DC, and "only" have the asynchronous replication between DCs - failures and partitions within one DC can be handled by SBR, fits the model of
