📝 Understanding the Results
- D1 Read: With read replication, reads are served from the nearest of 6 replica regions. Writes always go to primary.
- KV Read: Edge-cached at 300+ PoPs after first access. Reads are ~1-5ms from cache.
- KV Write: Writes go to central store, then propagate to edge (~60s eventual consistency).
- R2: No replication. All operations go to bucket's origin region. Use Cache API for fast reads.
