longDescription: |
Multi-region writes enable high availability but require careful consistency and conflict resolution. Using Bounded Staleness is an anti-pattern, as replication lag increases latency and coordination overhead. This setup undermines scalability, impacting performance and availability.
Opting into Business Critical Tier enables achieving 99.999% availability through either multi-region writes or PPAF. Multi-region writes supports all APIs but requires conflict-aware application design; PPAF requires the NoSQL API and newer SDKs.
