EU E-commerce with Arctickey

E-commerce teams use Redis-compatible infrastructure for carts, sessions, product cache, checkout locks, and order processing queues. Arctickey is designed for teams that want these workloads hosted in EU regions.

Common Workloads#

WorkloadPatternRetention guidance
Product cacheCache-aside with TTLMinutes to hours
Cart stateHash or JSON payload per cartExpire abandoned carts
Checkout locksShort-lived lock keysSeconds to minutes
Order jobsQueue with retriesKeep payload minimal
Rate limitsCounters per user/IPShort rolling windows

Cart Storage#

Terminal
HSET cart:c_123 sku_1 2 sku_2 1 EXPIRE cart:c_123 1209600

For logged-in customers, store the durable cart in your primary database and use Arctickey as the fast working copy.

Checkout Lock#

TypeScript
const lockKey = `checkout:lock:${cartId}`; const acquired = await redis.set(lockKey, "1", "EX", 60, "NX"); if (!acquired) { throw new Error("Checkout already in progress"); }

GDPR Notes#

  • Do not put emails, names, or addresses in key names.
  • Keep payment data out of Valkey; use your payment provider for card details.
  • Expire abandoned carts and checkout state automatically.
  • Keep order processing jobs minimal and fetch customer records from your primary database only when needed.
  • Document retention for carts, sessions, and queue payloads in your privacy notices.

Production Checklist#

  • Set TTLs for carts, checkout locks, sessions, and product cache.
  • Test cart deletion and account deletion workflows.
  • Use TLS connection strings in all app environments.
  • Keep production and staging instances separate.
  • Review GDPR Customer Guide before launch.
