GCP Only
All public clouds, on-prem and local
Architecture
Architected to span globally distributed data centers, yet still valuable in a single data center
Architected to resiliently span globally distributed data centers, while still being valuable in a single data center
Distributed transactions
Limited ability to optimize latency concerns for multi-region writes
Intelligent replication uses RAFT to place data and efficiently utilize available storage and compute resources
Multi-region writes
Limited ability to optimize latency concerns for multi-region writes
Advances in parallel commits and transaction pipelining reduce broad geographic transaction latencies
Data residency
