Cloudflare Maintenance

Monitoring

D1 Metrics

Check the D1 dashboard for:

• Query volume
• Error rates
• Storage size

R2 Metrics

Monitor:

• Class A / Class B operations
• Egress bandwidth
• Object count

Workers AI Limits

Track daily neuron usage:

curl -H "Authorization: Bearer $CF_API_TOKEN" \
  "https://api.cloudflare.com/client/v4/accounts/$CF_ACCOUNT_ID/ai/usage"

Scaling

D1

D1 automatically scales reads. For heavy write loads:

• Batch writes where possible
• Use transactions for related operations
• Consider sharding across multiple D1 databases

R2

R2 has no storage limit. Monitor operation counts:

• List operations are expensive — cache directory listings
• Use presigned URLs for direct client access

Cost Control

Service	Paid Tier Trigger
Workers AI	>10,000 neurons/day
D1	>5M reads/day or >100K writes/day
R2	>10M Class A ops/month
Queues	>1M ops/month

Set up billing alerts in the Cloudflare dashboard.

Backups

D1

Export snapshots:

wrangler d1 export docket-db --output=./backup.sql

R2

Use rclone or aws s3 sync:

aws s3 sync s3://docket-blobs ./r2-backup --endpoint-url=https://$CF_ACCOUNT_ID.r2.cloudflarestorage.com
